2022-09-08T14:46:06,173   Apache IoTDB (Database for Internet of Things) is an IoT native database with high performance for
2022-09-08T14:46:06,173   data management and analysis, deployable on the edge and the cloud. Due to its light-weight
2022-09-08T14:46:06,174   architecture, high performance and rich feature set together with its deep integration with
2022-09-08T14:46:06,174   Apache Hadoop, Spark and Flink, Apache IoTDB can meet the requirements of massive data storage,
2022-09-08T14:46:06,174   high-speed data ingestion and complex data analysis in the IoT industrial fields.

2022-09-08T14:46:06,175   ## Python Native API

2022-09-08T14:46:06,176   ### Requirements

2022-09-08T14:46:06,176   You have to install thrift (>=0.13) before using the package.



2022-09-08T14:46:06,178   ### How to use (Example)

2022-09-08T14:46:06,178   First, download the latest package: `pip3 install apache-iotdb`

2022-09-08T14:46:06,179   *Notice: If you are installing Python API v0.13.0, DO NOT install by `pip install apache-iotdb==0.13.0`, use `pip install apache-iotdb==0.13.0.post1` instead!*

2022-09-08T14:46:06,179   You can get an example of using the package to read and write data at here: [Example](https://github.com/apache/iotdb/blob/master/client-py/SessionExample.py)

2022-09-08T14:46:06,180   An example of aligned timeseries: [Aligned Timeseries Session Example](https://github.com/apache/iotdb/blob/master/client-py/SessionAlignedTimeseriesExample.py)

2022-09-08T14:46:06,181   (you need to add `import iotdb` in the head of the file)

2022-09-08T14:46:06,181   Or:

2022-09-08T14:46:06,182   ```python
2022-09-08T14:46:06,182   from iotdb.Session import Session

2022-09-08T14:46:06,183   ip = "127.0.0.1"
2022-09-08T14:46:06,183   port_ = "6667"
2022-09-08T14:46:06,183   username_ = "root"
2022-09-08T14:46:06,184   password_ = "root"
2022-09-08T14:46:06,184   session = Session(ip, port_, username_, password_)
2022-09-08T14:46:06,184   session.open(False)
2022-09-08T14:46:06,185   zone = session.get_time_zone()
2022-09-08T14:46:06,185   session.close()
2022-09-08T14:46:06,185   ```

2022-09-08T14:46:06,186   ### Initialization

2022-09-08T14:46:06,186   * Initialize a Session

2022-09-08T14:46:06,187   ```python
2022-09-08T14:46:06,187   session = Session(ip, port_, username_, password_, fetch_size=1024, zone_id="UTC+8")
2022-09-08T14:46:06,187   ```

2022-09-08T14:46:06,188   * Open a session, with a parameter to specify whether to enable RPC compression

2022-09-08T14:46:06,189   ```python
2022-09-08T14:46:06,189   session.open(enable_rpc_compression=False)
2022-09-08T14:46:06,189   ```

2022-09-08T14:46:06,190   Notice: this RPC compression status of client must comply with that of IoTDB server

2022-09-08T14:46:06,190   * Close a Session

2022-09-08T14:46:06,191   ```python
2022-09-08T14:46:06,191   session.close()
2022-09-08T14:46:06,192   ```

2022-09-08T14:46:06,192   ### Data Definition Interface (DDL Interface)

2022-09-08T14:46:06,193   #### Storage Group Management

2022-09-08T14:46:06,194   * Set storage group

2022-09-08T14:46:06,194   ```python
2022-09-08T14:46:06,194   session.set_storage_group(group_name)
2022-09-08T14:46:06,195   ```

2022-09-08T14:46:06,195   * Delete one or several storage groups

2022-09-08T14:46:06,196   ```python
2022-09-08T14:46:06,196   session.delete_storage_group(group_name)
2022-09-08T14:46:06,197   session.delete_storage_groups(group_name_lst)
2022-09-08T14:46:06,197   ```
2022-09-08T14:46:06,197   #### Timeseries Management

2022-09-08T14:46:06,198   * Create one or multiple timeseries

2022-09-08T14:46:06,198   ```python
2022-09-08T14:46:06,199   session.create_time_series(ts_path, data_type, encoding, compressor,
2022-09-08T14:46:06,199       props=None, tags=None, attributes=None, alias=None)

2022-09-08T14:46:06,200   session.create_multi_time_series(
2022-09-08T14:46:06,200       ts_path_lst, data_type_lst, encoding_lst, compressor_lst,
2022-09-08T14:46:06,200       props_lst=None, tags_lst=None, attributes_lst=None, alias_lst=None
2022-09-08T14:46:06,201   )
2022-09-08T14:46:06,201   ```

2022-09-08T14:46:06,202   * Create aligned timeseries

2022-09-08T14:46:06,202   ```python
2022-09-08T14:46:06,203   session.create_aligned_time_series(
2022-09-08T14:46:06,203       device_id, measurements_lst, data_type_lst, encoding_lst, compressor_lst
2022-09-08T14:46:06,203   )
2022-09-08T14:46:06,204   ```

2022-09-08T14:46:06,204   Attention: Alias of measurements are **not supported** currently.

2022-09-08T14:46:06,205   * Delete one or several timeseries

2022-09-08T14:46:06,205   ```python
2022-09-08T14:46:06,206   session.delete_time_series(paths_list)
2022-09-08T14:46:06,206   ```

2022-09-08T14:46:06,207   * Check whether the specific timeseries exists

2022-09-08T14:46:06,207   ```python
2022-09-08T14:46:06,208   session.check_time_series_exists(path)
2022-09-08T14:46:06,208   ```

2022-09-08T14:46:06,209   ### Data Manipulation Interface (DML Interface)

2022-09-08T14:46:06,209   #### Insert

2022-09-08T14:46:06,210   It is recommended to use insertTablet to help improve write efficiency.

2022-09-08T14:46:06,210   * Insert a Tablet，which is multiple rows of a device, each row has the same measurements
2022-09-08T14:46:06,211       * **Better Write Performance**
2022-09-08T14:46:06,211       * **Support null values**: fill the null value with any value, and then mark the null value via BitMap (from v0.13)


2022-09-08T14:46:06,212   We have two implementations of Tablet in Python API.

2022-09-08T14:46:06,213   * Normal Tablet

2022-09-08T14:46:06,213   ```python
2022-09-08T14:46:06,213   values_ = [
2022-09-08T14:46:06,214       [False, 10, 11, 1.1, 10011.1, "test01"],
2022-09-08T14:46:06,214       [True, 100, 11111, 1.25, 101.0, "test02"],
2022-09-08T14:46:06,214       [False, 100, 1, 188.1, 688.25, "test03"],
2022-09-08T14:46:06,215       [True, 0, 0, 0, 6.25, "test04"],
2022-09-08T14:46:06,215   ]
2022-09-08T14:46:06,215   timestamps_ = [1, 2, 3, 4]
2022-09-08T14:46:06,216   tablet_ = Tablet(
2022-09-08T14:46:06,216       device_id, measurements_, data_types_, values_, timestamps_
2022-09-08T14:46:06,216   )
2022-09-08T14:46:06,217   session.insert_tablet(tablet_)
2022-09-08T14:46:06,217   ```
2022-09-08T14:46:06,217   * Numpy Tablet

2022-09-08T14:46:06,218   Comparing with Tablet, Numpy Tablet is using [numpy.ndarray](https://numpy.org/doc/stable/reference/generated/numpy.ndarray.html) to record data.
2022-09-08T14:46:06,218   With less memory footprint and time cost of serialization, the insert performance will be better.

2022-09-08T14:46:06,219   **Notice**
2022-09-08T14:46:06,219   1. time and value columns in Tablet are ndarray.
2022-09-08T14:46:06,219   2. recommended to use the specific dtypes to each ndarray, see the example below
2022-09-08T14:46:06,220   (if not, the default dtypes are also ok).

2022-09-08T14:46:06,220   ```python
2022-09-08T14:46:06,221   import numpy as np
2022-09-08T14:46:06,221   data_types_ = [
2022-09-08T14:46:06,221       TSDataType.BOOLEAN,
2022-09-08T14:46:06,222       TSDataType.INT32,
2022-09-08T14:46:06,222       TSDataType.INT64,
2022-09-08T14:46:06,222       TSDataType.FLOAT,
2022-09-08T14:46:06,222       TSDataType.DOUBLE,
2022-09-08T14:46:06,223       TSDataType.TEXT,
2022-09-08T14:46:06,223   ]
2022-09-08T14:46:06,223   np_values_ = [
2022-09-08T14:46:06,224       np.array([False, True, False, True], TSDataType.BOOLEAN.np_dtype()),

2022-09-08T14:46:06,226   np_timestamps_ = np.array([1, 2, 3, 4], TSDataType.INT64.np_dtype())
2022-09-08T14:46:06,226   np_tablet_ = NumpyTablet(

2022-09-08T14:46:06,227   )
2022-09-08T14:46:06,227   session.insert_tablet(np_tablet_)
2022-09-08T14:46:06,227   ```

2022-09-08T14:46:06,228   * Insert multiple Tablets

2022-09-08T14:46:06,229   ```python
2022-09-08T14:46:06,229   session.insert_tablets(tablet_lst)
2022-09-08T14:46:06,229   ```

2022-09-08T14:46:06,230   * Insert a Record

2022-09-08T14:46:06,230   ```python
2022-09-08T14:46:06,231   session.insert_record(device_id, timestamp, measurements_, data_types_, values_)
2022-09-08T14:46:06,231   ```

2022-09-08T14:46:06,232   * Insert multiple Records

2022-09-08T14:46:06,232   ```python
2022-09-08T14:46:06,233   session.insert_records(
2022-09-08T14:46:06,233       device_ids_, time_list_, measurements_list_, data_type_list_, values_list_
2022-09-08T14:46:06,233   )
2022-09-08T14:46:06,233   ```

2022-09-08T14:46:06,234   * Insert multiple Records that belong to the same device.
2022-09-08T14:46:06,234     With type info the server has no need to do type inference, which leads a better performance


2022-09-08T14:46:06,235   ```python
2022-09-08T14:46:06,235   session.insert_records_of_one_device(device_id, time_list, measurements_list, data_types_list, values_list)
2022-09-08T14:46:06,236   ```

2022-09-08T14:46:06,236   #### Insert with type inference

2022-09-08T14:46:06,237   When the data is of String type, we can use the following interface to perform type inference based on the value of the value itself. For example, if value is "true" , it can be automatically inferred to be a boolean type. If value is "3.2" , it can be automatically inferred as a flout type. Without type information, server has to do type inference, which may cost some time.

2022-09-08T14:46:06,238   * Insert a Record, which contains multiple measurement value of a device at a timestamp

2022-09-08T14:46:06,238   ```python
2022-09-08T14:46:06,239   session.insert_str_record(device_id, timestamp, measurements, string_values)
2022-09-08T14:46:06,239   ```

2022-09-08T14:46:06,240   #### Insert of Aligned Timeseries

2022-09-08T14:46:06,240   The Insert of aligned timeseries uses interfaces like insert_aligned_XXX, and others are similar to the above interfaces:

2022-09-08T14:46:06,241   * insert_aligned_record
2022-09-08T14:46:06,241   * insert_aligned_records
2022-09-08T14:46:06,241   * insert_aligned_records_of_one_device
2022-09-08T14:46:06,242   * insert_aligned_tablet
2022-09-08T14:46:06,242   * insert_aligned_tablets


2022-09-08T14:46:06,243   ### IoTDB-SQL Interface

2022-09-08T14:46:06,244   * Execute query statement

2022-09-08T14:46:06,244   ```python
2022-09-08T14:46:06,244   session.execute_query_statement(sql)
2022-09-08T14:46:06,245   ```

2022-09-08T14:46:06,245   * Execute non query statement

2022-09-08T14:46:06,246   ```python
2022-09-08T14:46:06,246   session.execute_non_query_statement(sql)
2022-09-08T14:46:06,247   ```


2022-09-08T14:46:06,247   ### Pandas Support

2022-09-08T14:46:06,248   To easily transform a query result to a [Pandas Dataframe](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html)
2022-09-08T14:46:06,248   the SessionDataSet has a method `.todf()` which consumes the dataset and transforms it to a pandas dataframe.

2022-09-08T14:46:06,249   Example:

2022-09-08T14:46:06,250   ```python
2022-09-08T14:46:06,250   from iotdb.Session import Session

2022-09-08T14:46:06,251   ip = "127.0.0.1"
2022-09-08T14:46:06,251   port_ = "6667"
2022-09-08T14:46:06,251   username_ = "root"
2022-09-08T14:46:06,251   password_ = "root"
2022-09-08T14:46:06,252   session = Session(ip, port_, username_, password_)
2022-09-08T14:46:06,252   session.open(False)
2022-09-08T14:46:06,252   result = session.execute_query_statement("SELECT * FROM root.*")

2022-09-08T14:46:06,253   # Transform to Pandas Dataset
2022-09-08T14:46:06,253   df = result.todf()

2022-09-08T14:46:06,254   session.close()

2022-09-08T14:46:06,255   # Now you can work with the dataframe
2022-09-08T14:46:06,255   df = ...
2022-09-08T14:46:06,255   ```


2022-09-08T14:46:06,256   ### IoTDB Testcontainer

2022-09-08T14:46:06,257   The Test Support is based on the lib `testcontainers` (https://testcontainers-python.readthedocs.io/en/latest/index.html) which you need to install in your project if you want to use the feature.

2022-09-08T14:46:06,258   To start (and stop) an IoTDB Database in a Docker container simply do:
2022-09-08T14:46:06,258   ```python
2022-09-08T14:46:06,258   class MyTestCase(unittest.TestCase):

2022-09-08T14:46:06,259       def test_something(self):
2022-09-08T14:46:06,259           with IoTDBContainer() as c:
2022-09-08T14:46:06,260               session = Session("localhost", c.get_exposed_port(6667), "root", "root")
2022-09-08T14:46:06,260               session.open(False)
2022-09-08T14:46:06,260               result = session.execute_query_statement("SHOW TIMESERIES")
2022-09-08T14:46:06,260               print(result)
2022-09-08T14:46:06,261               session.close()
2022-09-08T14:46:06,261   ```

2022-09-08T14:46:06,262   by default it will load the image `apache/iotdb:latest`, if you want a specific version just pass it like e.g. `IoTDBContainer("apache/iotdb:0.12.0")` to get version `0.12.0` running.


2022-09-08T14:46:06,263   ## Developers

2022-09-08T14:46:06,263   ### Introduction

2022-09-08T14:46:06,264   This is an example of how to connect to IoTDB with python, using the thrift rpc interfaces. Things are almost the same on Windows or Linux, but pay attention to the difference like path separator.



2022-09-08T14:46:06,265   ### Prerequisites

2022-09-08T14:46:06,266   Python3.7 or later is preferred.

2022-09-08T14:46:06,266   You have to install Thrift (0.11.0 or later) to compile our thrift file into python code. Below is the official tutorial of installation, eventually, you should have a thrift executable.

2022-09-08T14:46:06,267   ```
2022-09-08T14:46:06,267   http://thrift.apache.org/docs/install/
2022-09-08T14:46:06,268   ```

2022-09-08T14:46:06,268   Before starting you need to install `requirements_dev.txt` in your python environment, e.g. by calling
2022-09-08T14:46:06,268   ```shell
2022-09-08T14:46:06,269   pip install -r requirements_dev.txt
2022-09-08T14:46:06,269   ```



2022-09-08T14:46:06,270   ### Compile the thrift library and Debug

2022-09-08T14:46:06,271   In the root of IoTDB's source code folder,  run `mvn clean generate-sources -pl client-py -am`.

2022-09-08T14:46:06,272   This will automatically delete and repopulate the folder `iotdb/thrift` with the generated thrift files.
2022-09-08T14:46:06,272   This folder is ignored from git and should **never be pushed to git!**

2022-09-08T14:46:06,272   **Notice** Do not upload `iotdb/thrift` to the git repo.




2022-09-08T14:46:06,274   ### Session Client & Example

2022-09-08T14:46:06,274   We packed up the Thrift interface in `client-py/src/iotdb/Session.py` (similar with its Java counterpart), also provided an example file `client-py/src/SessionExample.py` of how to use the session module. please read it carefully.


2022-09-08T14:46:06,275   Or, another simple example:

2022-09-08T14:46:06,276   ```python
2022-09-08T14:46:06,276   from iotdb.Session import Session

2022-09-08T14:46:06,277   ip = "127.0.0.1"
2022-09-08T14:46:06,277   port_ = "6667"
2022-09-08T14:46:06,277   username_ = "root"
2022-09-08T14:46:06,278   password_ = "root"
2022-09-08T14:46:06,278   session = Session(ip, port_, username_, password_)
2022-09-08T14:46:06,278   session.open(False)
2022-09-08T14:46:06,279   zone = session.get_time_zone()
2022-09-08T14:46:06,279   session.close()
2022-09-08T14:46:06,279   ```



2022-09-08T14:46:06,281   ### Tests

2022-09-08T14:46:06,281   Please add your custom tests in `tests` folder.

2022-09-08T14:46:06,282   To run all defined tests just type `pytest .` in the root folder.

2022-09-08T14:46:06,282   **Notice** Some tests need docker to be started on your system as a test instance is started in a docker container using [testcontainers](https://testcontainers-python.readthedocs.io/en/latest/index.html).



2022-09-08T14:46:06,284   ### Futher Tools

2022-09-08T14:46:06,284   [black](https://pypi.org/project/black/) and [flake8](https://pypi.org/project/flake8/) are installed for autoformatting and linting.
2022-09-08T14:46:06,285   Both can be run by `black .` or `flake8 .` respectively.



2022-09-08T14:46:06,286   ## Releasing

2022-09-08T14:46:06,287   To do a release just ensure that you have the right set of generated thrift files.
2022-09-08T14:46:06,287   Then run linting and auto-formatting.
2022-09-08T14:46:06,287   Then, ensure that all tests work (via `pytest .`).
2022-09-08T14:46:06,287   Then you are good to go to do a release!



2022-09-08T14:46:06,289   ### Preparing your environment

2022-09-08T14:46:06,289   First, install all necessary dev dependencies via `pip install -r requirements_dev.txt`.



2022-09-08T14:46:06,290   ### Doing the Release

2022-09-08T14:46:06,291   There is a convenient script `release.sh` to do all steps for a release.
2022-09-08T14:46:06,291   Namely, these are

2022-09-08T14:46:06,292   * Remove all transient directories from last release (if exists)
2022-09-08T14:46:06,292   * (Re-)generate all generated sources via mvn
2022-09-08T14:46:06,293   * Run Linting (flake8)
2022-09-08T14:46:06,293   * Run Tests via pytest
2022-09-08T14:46:06,293   * Build
2022-09-08T14:46:06,293   * Release to pypi

2022-09-08T14:46:18,525   Apache IoTDB (Database for Internet of Things) is an IoT native database with high performance for
2022-09-08T14:46:18,526   data management and analysis, deployable on the edge and the cloud. Due to its light-weight
2022-09-08T14:46:18,526   architecture, high performance and rich feature set together with its deep integration with
2022-09-08T14:46:18,526   Apache Hadoop, Spark and Flink, Apache IoTDB can meet the requirements of massive data storage,
2022-09-08T14:46:18,527   high-speed data ingestion and complex data analysis in the IoT industrial fields.

2022-09-08T14:46:18,527   ## Python Native API

2022-09-08T14:46:18,528   ### Requirements

2022-09-08T14:46:18,528   You have to install thrift (>=0.13) before using the package.



2022-09-08T14:46:18,530   ### How to use (Example)

2022-09-08T14:46:18,530   First, download the latest package: `pip3 install apache-iotdb`

2022-09-08T14:46:18,531   *Notice: If you are installing Python API v0.13.0, DO NOT install by `pip install apache-iotdb==0.13.0`, use `pip install apache-iotdb==0.13.0.post1` instead!*

2022-09-08T14:46:18,531   You can get an example of using the package to read and write data at here: [Example](https://github.com/apache/iotdb/blob/master/client-py/SessionExample.py)

2022-09-08T14:46:18,532   An example of aligned timeseries: [Aligned Timeseries Session Example](https://github.com/apache/iotdb/blob/master/client-py/SessionAlignedTimeseriesExample.py)

2022-09-08T14:46:18,533   (you need to add `import iotdb` in the head of the file)

2022-09-08T14:46:18,533   Or:

2022-09-08T14:46:18,534   ```python
2022-09-08T14:46:18,534   from iotdb.Session import Session

2022-09-08T14:46:18,535   ip = "127.0.0.1"
2022-09-08T14:46:18,535   port_ = "6667"
2022-09-08T14:46:18,535   username_ = "root"
2022-09-08T14:46:18,535   password_ = "root"
2022-09-08T14:46:18,536   session = Session(ip, port_, username_, password_)
2022-09-08T14:46:18,536   session.open(False)
2022-09-08T14:46:18,536   zone = session.get_time_zone()
2022-09-08T14:46:18,537   session.close()
2022-09-08T14:46:18,537   ```

2022-09-08T14:46:18,538   ### Initialization

2022-09-08T14:46:18,538   * Initialize a Session

2022-09-08T14:46:18,539   ```python
2022-09-08T14:46:18,539   session = Session(ip, port_, username_, password_, fetch_size=1024, zone_id="UTC+8")
2022-09-08T14:46:18,539   ```

2022-09-08T14:46:18,540   * Open a session, with a parameter to specify whether to enable RPC compression

2022-09-08T14:46:18,541   ```python
2022-09-08T14:46:18,541   session.open(enable_rpc_compression=False)
2022-09-08T14:46:18,541   ```

2022-09-08T14:46:18,542   Notice: this RPC compression status of client must comply with that of IoTDB server

2022-09-08T14:46:18,543   * Close a Session

2022-09-08T14:46:18,543   ```python
2022-09-08T14:46:18,543   session.close()
2022-09-08T14:46:18,544   ```

2022-09-08T14:46:18,544   ### Data Definition Interface (DDL Interface)

2022-09-08T14:46:18,545   #### Storage Group Management

2022-09-08T14:46:18,546   * Set storage group

2022-09-08T14:46:18,546   ```python
2022-09-08T14:46:18,547   session.set_storage_group(group_name)
2022-09-08T14:46:18,547   ```

2022-09-08T14:46:18,548   * Delete one or several storage groups

2022-09-08T14:46:18,548   ```python
2022-09-08T14:46:18,548   session.delete_storage_group(group_name)
2022-09-08T14:46:18,549   session.delete_storage_groups(group_name_lst)
2022-09-08T14:46:18,549   ```
2022-09-08T14:46:18,549   #### Timeseries Management

2022-09-08T14:46:18,550   * Create one or multiple timeseries

2022-09-08T14:46:18,551   ```python
2022-09-08T14:46:18,551   session.create_time_series(ts_path, data_type, encoding, compressor,
2022-09-08T14:46:18,551       props=None, tags=None, attributes=None, alias=None)

2022-09-08T14:46:18,552   session.create_multi_time_series(
2022-09-08T14:46:18,552       ts_path_lst, data_type_lst, encoding_lst, compressor_lst,
2022-09-08T14:46:18,552       props_lst=None, tags_lst=None, attributes_lst=None, alias_lst=None
2022-09-08T14:46:18,553   )
2022-09-08T14:46:18,553   ```

2022-09-08T14:46:18,554   * Create aligned timeseries

2022-09-08T14:46:18,554   ```python
2022-09-08T14:46:18,555   session.create_aligned_time_series(
2022-09-08T14:46:18,555       device_id, measurements_lst, data_type_lst, encoding_lst, compressor_lst
2022-09-08T14:46:18,555   )
2022-09-08T14:46:18,555   ```

2022-09-08T14:46:18,556   Attention: Alias of measurements are **not supported** currently.

2022-09-08T14:46:18,557   * Delete one or several timeseries

2022-09-08T14:46:18,557   ```python
2022-09-08T14:46:18,558   session.delete_time_series(paths_list)
2022-09-08T14:46:18,558   ```

2022-09-08T14:46:18,558   * Check whether the specific timeseries exists

2022-09-08T14:46:18,559   ```python
2022-09-08T14:46:18,559   session.check_time_series_exists(path)
2022-09-08T14:46:18,560   ```

2022-09-08T14:46:18,560   ### Data Manipulation Interface (DML Interface)

2022-09-08T14:46:18,561   #### Insert

2022-09-08T14:46:18,561   It is recommended to use insertTablet to help improve write efficiency.

2022-09-08T14:46:18,562   * Insert a Tablet，which is multiple rows of a device, each row has the same measurements
2022-09-08T14:46:18,562       * **Better Write Performance**
2022-09-08T14:46:18,563       * **Support null values**: fill the null value with any value, and then mark the null value via BitMap (from v0.13)


2022-09-08T14:46:18,564   We have two implementations of Tablet in Python API.

2022-09-08T14:46:18,564   * Normal Tablet

2022-09-08T14:46:18,565   ```python
2022-09-08T14:46:18,565   values_ = [
2022-09-08T14:46:18,565       [False, 10, 11, 1.1, 10011.1, "test01"],
2022-09-08T14:46:18,566       [True, 100, 11111, 1.25, 101.0, "test02"],
2022-09-08T14:46:18,566       [False, 100, 1, 188.1, 688.25, "test03"],
2022-09-08T14:46:18,566       [True, 0, 0, 0, 6.25, "test04"],
2022-09-08T14:46:18,567   ]
2022-09-08T14:46:18,567   timestamps_ = [1, 2, 3, 4]
2022-09-08T14:46:18,567   tablet_ = Tablet(
2022-09-08T14:46:18,567       device_id, measurements_, data_types_, values_, timestamps_
2022-09-08T14:46:18,568   )
2022-09-08T14:46:18,568   session.insert_tablet(tablet_)
2022-09-08T14:46:18,568   ```
2022-09-08T14:46:18,569   * Numpy Tablet

2022-09-08T14:46:18,569   Comparing with Tablet, Numpy Tablet is using [numpy.ndarray](https://numpy.org/doc/stable/reference/generated/numpy.ndarray.html) to record data.
2022-09-08T14:46:18,570   With less memory footprint and time cost of serialization, the insert performance will be better.

2022-09-08T14:46:18,570   **Notice**
2022-09-08T14:46:18,571   1. time and value columns in Tablet are ndarray.
2022-09-08T14:46:18,571   2. recommended to use the specific dtypes to each ndarray, see the example below
2022-09-08T14:46:18,571   (if not, the default dtypes are also ok).

2022-09-08T14:46:18,572   ```python
2022-09-08T14:46:18,572   import numpy as np
2022-09-08T14:46:18,573   data_types_ = [
2022-09-08T14:46:18,573       TSDataType.BOOLEAN,
2022-09-08T14:46:18,573       TSDataType.INT32,
2022-09-08T14:46:18,574       TSDataType.INT64,
2022-09-08T14:46:18,574       TSDataType.FLOAT,
2022-09-08T14:46:18,574       TSDataType.DOUBLE,
2022-09-08T14:46:18,574       TSDataType.TEXT,
2022-09-08T14:46:18,575   ]
2022-09-08T14:46:18,575   np_values_ = [
2022-09-08T14:46:18,575       np.array([False, True, False, True], TSDataType.BOOLEAN.np_dtype()),
2022-09-08T14:46:18,576       np.array([10, 100, 100, 0], TSDataType.INT32.np_dtype()),
2022-09-08T14:46:18,576       np.array([11, 11111, 1, 0], TSDataType.INT64.np_dtype()),
2022-09-08T14:46:18,576       np.array([1.1, 1.25, 188.1, 0], TSDataType.FLOAT.np_dtype()),
2022-09-08T14:46:18,577       np.array([10011.1, 101.0, 688.25, 6.25], TSDataType.DOUBLE.np_dtype()),
2022-09-08T14:46:18,577       np.array(["test01", "test02", "test03", "test04"], TSDataType.TEXT.np_dtype()),
2022-09-08T14:46:18,577   ]
2022-09-08T14:46:18,577   np_timestamps_ = np.array([1, 2, 3, 4], TSDataType.INT64.np_dtype())
2022-09-08T14:46:18,578   np_tablet_ = NumpyTablet(
2022-09-08T14:46:18,578     "root.sg_test_01.d_02", measurements_, data_types_, np_values_, np_timestamps_
2022-09-08T14:46:18,578   )
2022-09-08T14:46:18,579   session.insert_tablet(np_tablet_)
2022-09-08T14:46:18,579   ```

2022-09-08T14:46:18,580   * Insert multiple Tablets

2022-09-08T14:46:18,580   ```python
2022-09-08T14:46:18,581   session.insert_tablets(tablet_lst)
2022-09-08T14:46:18,581   ```

2022-09-08T14:46:18,581   * Insert a Record

2022-09-08T14:46:18,582   ```python
2022-09-08T14:46:18,582   session.insert_record(device_id, timestamp, measurements_, data_types_, values_)
2022-09-08T14:46:18,583   ```

2022-09-08T14:46:18,583   * Insert multiple Records

2022-09-08T14:46:18,584   ```python
2022-09-08T14:46:18,584   session.insert_records(
2022-09-08T14:46:18,585       device_ids_, time_list_, measurements_list_, data_type_list_, values_list_
2022-09-08T14:46:18,585   )
2022-09-08T14:46:18,585   ```

2022-09-08T14:46:18,586   * Insert multiple Records that belong to the same device.
2022-09-08T14:46:18,586     With type info the server has no need to do type inference, which leads a better performance


2022-09-08T14:46:18,587   ```python
2022-09-08T14:46:18,587   session.insert_records_of_one_device(device_id, time_list, measurements_list, data_types_list, values_list)
2022-09-08T14:46:18,588   ```

2022-09-08T14:46:18,588   #### Insert with type inference

2022-09-08T14:46:18,589   When the data is of String type, we can use the following interface to perform type inference based on the value of the value itself. For example, if value is "true" , it can be automatically inferred to be a boolean type. If value is "3.2" , it can be automatically inferred as a flout type. Without type information, server has to do type inference, which may cost some time.

2022-09-08T14:46:18,589   * Insert a Record, which contains multiple measurement value of a device at a timestamp

2022-09-08T14:46:18,590   ```python
2022-09-08T14:46:18,591   session.insert_str_record(device_id, timestamp, measurements, string_values)
2022-09-08T14:46:18,591   ```

2022-09-08T14:46:18,592   #### Insert of Aligned Timeseries

2022-09-08T14:46:18,592   The Insert of aligned timeseries uses interfaces like insert_aligned_XXX, and others are similar to the above interfaces:

2022-09-08T14:46:18,593   * insert_aligned_record
2022-09-08T14:46:18,593   * insert_aligned_records
2022-09-08T14:46:18,593   * insert_aligned_records_of_one_device
2022-09-08T14:46:18,594   * insert_aligned_tablet
2022-09-08T14:46:18,594   * insert_aligned_tablets


2022-09-08T14:46:18,595   ### IoTDB-SQL Interface

2022-09-08T14:46:18,595   * Execute query statement

2022-09-08T14:46:18,596   ```python
2022-09-08T14:46:18,596   session.execute_query_statement(sql)
2022-09-08T14:46:18,597   ```

2022-09-08T14:46:18,597   * Execute non query statement

2022-09-08T14:46:18,598   ```python
2022-09-08T14:46:18,598   session.execute_non_query_statement(sql)
2022-09-08T14:46:18,599   ```


2022-09-08T14:46:18,600   ### Pandas Support

2022-09-08T14:46:18,600   To easily transform a query result to a [Pandas Dataframe](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html)
2022-09-08T14:46:18,600   the SessionDataSet has a method `.todf()` which consumes the dataset and transforms it to a pandas dataframe.

2022-09-08T14:46:18,601   Example:

2022-09-08T14:46:18,602   ```python
2022-09-08T14:46:18,602   from iotdb.Session import Session

2022-09-08T14:46:18,602   ip = "127.0.0.1"
2022-09-08T14:46:18,603   port_ = "6667"
2022-09-08T14:46:18,603   username_ = "root"
2022-09-08T14:46:18,603   password_ = "root"
2022-09-08T14:46:18,604   session = Session(ip, port_, username_, password_)
2022-09-08T14:46:18,604   session.open(False)
2022-09-08T14:46:18,604   result = session.execute_query_statement("SELECT * FROM root.*")

2022-09-08T14:46:18,605   # Transform to Pandas Dataset
2022-09-08T14:46:18,605   df = result.todf()

2022-09-08T14:46:18,606   session.close()

2022-09-08T14:46:18,606   # Now you can work with the dataframe
2022-09-08T14:46:18,607   df = ...
2022-09-08T14:46:18,607   ```


2022-09-08T14:46:18,608   ### IoTDB Testcontainer

2022-09-08T14:46:18,608   The Test Support is based on the lib `testcontainers` (https://testcontainers-python.readthedocs.io/en/latest/index.html) which you need to install in your project if you want to use the feature.

2022-09-08T14:46:18,609   To start (and stop) an IoTDB Database in a Docker container simply do:
2022-09-08T14:46:18,609   ```python
2022-09-08T14:46:18,610   class MyTestCase(unittest.TestCase):

2022-09-08T14:46:18,610       def test_something(self):
2022-09-08T14:46:18,611           with IoTDBContainer() as c:
2022-09-08T14:46:18,611               session = Session("localhost", c.get_exposed_port(6667), "root", "root")
2022-09-08T14:46:18,611               session.open(False)
2022-09-08T14:46:18,612               result = session.execute_query_statement("SHOW TIMESERIES")
2022-09-08T14:46:18,612               print(result)
2022-09-08T14:46:18,612               session.close()
2022-09-08T14:46:18,612   ```

2022-09-08T14:46:18,613   by default it will load the image `apache/iotdb:latest`, if you want a specific version just pass it like e.g. `IoTDBContainer("apache/iotdb:0.12.0")` to get version `0.12.0` running.


2022-09-08T14:46:18,614   ## Developers

2022-09-08T14:46:18,615   ### Introduction

2022-09-08T14:46:18,615   This is an example of how to connect to IoTDB with python, using the thrift rpc interfaces. Things are almost the same on Windows or Linux, but pay attention to the difference like path separator.



2022-09-08T14:46:18,616   ### Prerequisites

2022-09-08T14:46:18,617   Python3.7 or later is preferred.

2022-09-08T14:46:18,617   You have to install Thrift (0.11.0 or later) to compile our thrift file into python code. Below is the official tutorial of installation, eventually, you should have a thrift executable.

2022-09-08T14:46:18,618   ```
2022-09-08T14:46:18,618   http://thrift.apache.org/docs/install/
2022-09-08T14:46:18,619   ```

2022-09-08T14:46:18,619   Before starting you need to install `requirements_dev.txt` in your python environment, e.g. by calling
2022-09-08T14:46:18,620   ```shell
2022-09-08T14:46:18,620   pip install -r requirements_dev.txt
2022-09-08T14:46:18,620   ```



2022-09-08T14:46:18,622   ### Compile the thrift library and Debug

2022-09-08T14:46:18,622   In the root of IoTDB's source code folder,  run `mvn clean generate-sources -pl client-py -am`.

2022-09-08T14:46:18,623   This will automatically delete and repopulate the folder `iotdb/thrift` with the generated thrift files.
2022-09-08T14:46:18,623   This folder is ignored from git and should **never be pushed to git!**

2022-09-08T14:46:18,624   **Notice** Do not upload `iotdb/thrift` to the git repo.




2022-09-08T14:46:18,625   ### Session Client & Example

2022-09-08T14:46:18,626   We packed up the Thrift interface in `client-py/src/iotdb/Session.py` (similar with its Java counterpart), also provided an example file `client-py/src/SessionExample.py` of how to use the session module. please read it carefully.


2022-09-08T14:46:18,627   Or, another simple example:

2022-09-08T14:46:18,628   ```python
2022-09-08T14:46:18,628   from iotdb.Session import Session

2022-09-08T14:46:18,629   ip = "127.0.0.1"
2022-09-08T14:46:18,629   port_ = "6667"
2022-09-08T14:46:18,629   username_ = "root"
2022-09-08T14:46:18,630   password_ = "root"
2022-09-08T14:46:18,630   session = Session(ip, port_, username_, password_)
2022-09-08T14:46:18,630   session.open(False)
2022-09-08T14:46:18,631   zone = session.get_time_zone()
2022-09-08T14:46:18,631   session.close()
2022-09-08T14:46:18,631   ```



2022-09-08T14:46:18,632   ### Tests

2022-09-08T14:46:18,633   Please add your custom tests in `tests` folder.

2022-09-08T14:46:18,633   To run all defined tests just type `pytest .` in the root folder.

2022-09-08T14:46:18,634   **Notice** Some tests need docker to be started on your system as a test instance is started in a docker container using [testcontainers](https://testcontainers-python.readthedocs.io/en/latest/index.html).



2022-09-08T14:46:18,635   ### Futher Tools

2022-09-08T14:46:18,636   [black](https://pypi.org/project/black/) and [flake8](https://pypi.org/project/flake8/) are installed for autoformatting and linting.
2022-09-08T14:46:18,636   Both can be run by `black .` or `flake8 .` respectively.



2022-09-08T14:46:18,637   ## Releasing

2022-09-08T14:46:18,638   To do a release just ensure that you have the right set of generated thrift files.
2022-09-08T14:46:18,638   Then run linting and auto-formatting.
2022-09-08T14:46:18,639   Then, ensure that all tests work (via `pytest .`).
2022-09-08T14:46:18,639   Then you are good to go to do a release!



2022-09-08T14:46:18,640   ### Preparing your environment

2022-09-08T14:46:18,641   First, install all necessary dev dependencies via `pip install -r requirements_dev.txt`.



2022-09-08T14:46:18,642   ### Doing the Release

2022-09-08T14:46:18,642   There is a convenient script `release.sh` to do all steps for a release.
2022-09-08T14:46:18,643   Namely, these are

2022-09-08T14:46:18,643   * Remove all transient directories from last release (if exists)
2022-09-08T14:46:18,644   * (Re-)generate all generated sources via mvn
2022-09-08T14:46:18,644   * Run Linting (flake8)
2022-09-08T14:46:18,644   * Run Tests via pytest
2022-09-08T14:46:18,644   * Build
2022-09-08T14:46:18,645   * Release to pypi

2022-09-08T14:46:31,442   Apache IoTDB (Database for Internet of Things) is an IoT native database with high performance for
2022-09-08T14:46:31,443   data management and analysis, deployable on the edge and the cloud. Due to its light-weight
2022-09-08T14:46:31,443   architecture, high performance and rich feature set together with its deep integration with
2022-09-08T14:46:31,444   Apache Hadoop, Spark and Flink, Apache IoTDB can meet the requirements of massive data storage,
2022-09-08T14:46:31,444   high-speed data ingestion and complex data analysis in the IoT industrial fields.

2022-09-08T14:46:31,445   ## Python Native API

2022-09-08T14:46:31,446   ### Requirements

2022-09-08T14:46:31,446   You have to install thrift (>=0.13) before using the package.



2022-09-08T14:46:31,448   ### How to use (Example)

2022-09-08T14:46:31,448   First, download the latest package: `pip3 install apache-iotdb`

2022-09-08T14:46:31,449   *Notice: If you are installing Python API v0.13.0, DO NOT install by `pip install apache-iotdb==0.13.0`, use `pip install apache-iotdb==0.13.0.post1` instead!*

2022-09-08T14:46:31,450   You can get an example of using the package to read and write data at here: [Example](https://github.com/apache/iotdb/blob/master/client-py/SessionExample.py)

2022-09-08T14:46:31,451   An example of aligned timeseries: [Aligned Timeseries Session Example](https://github.com/apache/iotdb/blob/master/client-py/SessionAlignedTimeseriesExample.py)

2022-09-08T14:46:31,451   (you need to add `import iotdb` in the head of the file)

2022-09-08T14:46:31,452   Or:

2022-09-08T14:46:31,453   ```python
2022-09-08T14:46:31,453   from iotdb.Session import Session

2022-09-08T14:46:31,454   ip = "127.0.0.1"
2022-09-08T14:46:31,455   port_ = "6667"
2022-09-08T14:46:31,455   username_ = "root"
2022-09-08T14:46:31,456   password_ = "root"
2022-09-08T14:46:31,456   session = Session(ip, port_, username_, password_)
2022-09-08T14:46:31,456   session.open(False)
2022-09-08T14:46:31,457   zone = session.get_time_zone()
2022-09-08T14:46:31,457   session.close()
2022-09-08T14:46:31,457   ```

2022-09-08T14:46:31,458   ### Initialization

2022-09-08T14:46:31,459   * Initialize a Session

2022-09-08T14:46:31,459   ```python
2022-09-08T14:46:31,460   session = Session(ip, port_, username_, password_, fetch_size=1024, zone_id="UTC+8")
2022-09-08T14:46:31,460   ```

2022-09-08T14:46:31,461   * Open a session, with a parameter to specify whether to enable RPC compression

2022-09-08T14:46:31,461   ```python
2022-09-08T14:46:31,462   session.open(enable_rpc_compression=False)
2022-09-08T14:46:31,462   ```

2022-09-08T14:46:31,462   Notice: this RPC compression status of client must comply with that of IoTDB server

2022-09-08T14:46:31,463   * Close a Session

2022-09-08T14:46:31,464   ```python
2022-09-08T14:46:31,464   session.close()
2022-09-08T14:46:31,464   ```

2022-09-08T14:46:31,465   ### Data Definition Interface (DDL Interface)

2022-09-08T14:46:31,466   #### Storage Group Management

2022-09-08T14:46:31,466   * Set storage group

2022-09-08T14:46:31,467   ```python
2022-09-08T14:46:31,467   session.set_storage_group(group_name)
2022-09-08T14:46:31,467   ```

2022-09-08T14:46:31,468   * Delete one or several storage groups

2022-09-08T14:46:31,469   ```python
2022-09-08T14:46:31,469   session.delete_storage_group(group_name)
2022-09-08T14:46:31,469   session.delete_storage_groups(group_name_lst)
2022-09-08T14:46:31,470   ```
2022-09-08T14:46:31,470   #### Timeseries Management

2022-09-08T14:46:31,471   * Create one or multiple timeseries

2022-09-08T14:46:31,471   ```python
2022-09-08T14:46:31,471   session.create_time_series(ts_path, data_type, encoding, compressor,
2022-09-08T14:46:31,472       props=None, tags=None, attributes=None, alias=None)

2022-09-08T14:46:31,472   session.create_multi_time_series(
2022-09-08T14:46:31,473       ts_path_lst, data_type_lst, encoding_lst, compressor_lst,
2022-09-08T14:46:31,473       props_lst=None, tags_lst=None, attributes_lst=None, alias_lst=None
2022-09-08T14:46:31,473   )
2022-09-08T14:46:31,474   ```

2022-09-08T14:46:31,474   * Create aligned timeseries

2022-09-08T14:46:31,475   ```python
2022-09-08T14:46:31,475   session.create_aligned_time_series(
2022-09-08T14:46:31,476       device_id, measurements_lst, data_type_lst, encoding_lst, compressor_lst
2022-09-08T14:46:31,476   )
2022-09-08T14:46:31,476   ```

2022-09-08T14:46:31,477   Attention: Alias of measurements are **not supported** currently.

2022-09-08T14:46:31,478   * Delete one or several timeseries

2022-09-08T14:46:31,478   ```python
2022-09-08T14:46:31,478   session.delete_time_series(paths_list)
2022-09-08T14:46:31,479   ```

2022-09-08T14:46:31,479   * Check whether the specific timeseries exists

2022-09-08T14:46:31,480   ```python
2022-09-08T14:46:31,480   session.check_time_series_exists(path)
2022-09-08T14:46:31,481   ```

2022-09-08T14:46:31,481   ### Data Manipulation Interface (DML Interface)

2022-09-08T14:46:31,482   #### Insert

2022-09-08T14:46:31,482   It is recommended to use insertTablet to help improve write efficiency.

2022-09-08T14:46:31,483   * Insert a Tablet，which is multiple rows of a device, each row has the same measurements
2022-09-08T14:46:31,483       * **Better Write Performance**
2022-09-08T14:46:31,484       * **Support null values**: fill the null value with any value, and then mark the null value via BitMap (from v0.13)


2022-09-08T14:46:31,485   We have two implementations of Tablet in Python API.

2022-09-08T14:46:31,485   * Normal Tablet

2022-09-08T14:46:31,486   ```python
2022-09-08T14:46:31,486   values_ = [
2022-09-08T14:46:31,486       [False, 10, 11, 1.1, 10011.1, "test01"],
2022-09-08T14:46:31,487       [True, 100, 11111, 1.25, 101.0, "test02"],

2022-09-08T14:46:31,488       [True, 0, 0, 0, 6.25, "test04"],
2022-09-08T14:46:31,488   ]
2022-09-08T14:46:31,488   timestamps_ = [1, 2, 3, 4]
2022-09-08T14:46:31,489   tablet_ = Tablet(
2022-09-08T14:46:31,489       device_id, measurements_, data_types_, values_, timestamps_
2022-09-08T14:46:31,490   )
2022-09-08T14:46:31,490   session.insert_tablet(tablet_)
2022-09-08T14:46:31,490   ```
2022-09-08T14:46:31,491   * Numpy Tablet

2022-09-08T14:46:31,491   Comparing with Tablet, Numpy Tablet is using [numpy.ndarray](https://numpy.org/doc/stable/reference/generated/numpy.ndarray.html) to record data.
2022-09-08T14:46:31,492   With less memory footprint and time cost of serialization, the insert performance will be better.

2022-09-08T14:46:31,493   **Notice**
2022-09-08T14:46:31,493   1. time and value columns in Tablet are ndarray.
2022-09-08T14:46:31,493   2. recommended to use the specific dtypes to each ndarray, see the example below
2022-09-08T14:46:31,494   (if not, the default dtypes are also ok).

2022-09-08T14:46:31,494   ```python
2022-09-08T14:46:31,495   import numpy as np
2022-09-08T14:46:31,495   data_types_ = [

2022-09-08T14:46:31,498       TSDataType.TEXT,
2022-09-08T14:46:31,498   ]
2022-09-08T14:46:31,498   np_values_ = [
2022-09-08T14:46:31,499       np.array([False, True, False, True], TSDataType.BOOLEAN.np_dtype()),

2022-09-08T14:46:31,500       np.array([1.1, 1.25, 188.1, 0], TSDataType.FLOAT.np_dtype()),
2022-09-08T14:46:31,501       np.array([10011.1, 101.0, 688.25, 6.25], TSDataType.DOUBLE.np_dtype()),

2022-09-08T14:46:31,501   ]
2022-09-08T14:46:31,502   np_timestamps_ = np.array([1, 2, 3, 4], TSDataType.INT64.np_dtype())
2022-09-08T14:46:31,502   np_tablet_ = NumpyTablet(
2022-09-08T14:46:31,503     "root.sg_test_01.d_02", measurements_, data_types_, np_values_, np_timestamps_
2022-09-08T14:46:31,503   )
2022-09-08T14:46:31,503   session.insert_tablet(np_tablet_)
2022-09-08T14:46:31,504   ```

2022-09-08T14:46:31,504   * Insert multiple Tablets

2022-09-08T14:46:31,505   ```python
2022-09-08T14:46:31,505   session.insert_tablets(tablet_lst)
2022-09-08T14:46:31,506   ```

2022-09-08T14:46:31,506   * Insert a Record

2022-09-08T14:46:31,507   ```python
2022-09-08T14:46:31,507   session.insert_record(device_id, timestamp, measurements_, data_types_, values_)
2022-09-08T14:46:31,507   ```

2022-09-08T14:46:31,508   * Insert multiple Records

2022-09-08T14:46:31,509   ```python
2022-09-08T14:46:31,509   session.insert_records(
2022-09-08T14:46:31,509       device_ids_, time_list_, measurements_list_, data_type_list_, values_list_
2022-09-08T14:46:31,510   )
2022-09-08T14:46:31,510   ```

2022-09-08T14:46:31,511   * Insert multiple Records that belong to the same device.
2022-09-08T14:46:31,511     With type info the server has no need to do type inference, which leads a better performance


2022-09-08T14:46:31,512   ```python
2022-09-08T14:46:31,512   session.insert_records_of_one_device(device_id, time_list, measurements_list, data_types_list, values_list)
2022-09-08T14:46:31,512   ```

2022-09-08T14:46:31,513   #### Insert with type inference

2022-09-08T14:46:31,514   When the data is of String type, we can use the following interface to perform type inference based on the value of the value itself. For example, if value is "true" , it can be automatically inferred to be a boolean type. If value is "3.2" , it can be automatically inferred as a flout type. Without type information, server has to do type inference, which may cost some time.

2022-09-08T14:46:31,514   * Insert a Record, which contains multiple measurement value of a device at a timestamp

2022-09-08T14:46:31,515   ```python
2022-09-08T14:46:31,515   session.insert_str_record(device_id, timestamp, measurements, string_values)
2022-09-08T14:46:31,516   ```

2022-09-08T14:46:31,516   #### Insert of Aligned Timeseries

2022-09-08T14:46:31,517   The Insert of aligned timeseries uses interfaces like insert_aligned_XXX, and others are similar to the above interfaces:

2022-09-08T14:46:31,517   * insert_aligned_record
2022-09-08T14:46:31,518   * insert_aligned_records
2022-09-08T14:46:31,518   * insert_aligned_records_of_one_device
2022-09-08T14:46:31,518   * insert_aligned_tablet
2022-09-08T14:46:31,519   * insert_aligned_tablets


2022-09-08T14:46:31,520   ### IoTDB-SQL Interface

2022-09-08T14:46:31,520   * Execute query statement

2022-09-08T14:46:31,521   ```python
2022-09-08T14:46:31,521   session.execute_query_statement(sql)
2022-09-08T14:46:31,521   ```

2022-09-08T14:46:31,522   * Execute non query statement

2022-09-08T14:46:31,523   ```python
2022-09-08T14:46:31,523   session.execute_non_query_statement(sql)
2022-09-08T14:46:31,523   ```


2022-09-08T14:46:31,524   ### Pandas Support

2022-09-08T14:46:31,525   To easily transform a query result to a [Pandas Dataframe](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html)
2022-09-08T14:46:31,525   the SessionDataSet has a method `.todf()` which consumes the dataset and transforms it to a pandas dataframe.

2022-09-08T14:46:31,526   Example:

2022-09-08T14:46:31,526   ```python
2022-09-08T14:46:31,526   from iotdb.Session import Session

2022-09-08T14:46:31,527   ip = "127.0.0.1"
2022-09-08T14:46:31,527   port_ = "6667"
2022-09-08T14:46:31,528   username_ = "root"
2022-09-08T14:46:31,528   password_ = "root"
2022-09-08T14:46:31,528   session = Session(ip, port_, username_, password_)
2022-09-08T14:46:31,529   session.open(False)
2022-09-08T14:46:31,529   result = session.execute_query_statement("SELECT * FROM root.*")

2022-09-08T14:46:31,530   # Transform to Pandas Dataset
2022-09-08T14:46:31,530   df = result.todf()

2022-09-08T14:46:31,530   session.close()

2022-09-08T14:46:31,531   # Now you can work with the dataframe
2022-09-08T14:46:31,531   df = ...
2022-09-08T14:46:31,532   ```


2022-09-08T14:46:31,533   ### IoTDB Testcontainer

2022-09-08T14:46:31,533   The Test Support is based on the lib `testcontainers` (https://testcontainers-python.readthedocs.io/en/latest/index.html) which you need to install in your project if you want to use the feature.

2022-09-08T14:46:31,534   To start (and stop) an IoTDB Database in a Docker container simply do:
2022-09-08T14:46:31,534   ```python
2022-09-08T14:46:31,534   class MyTestCase(unittest.TestCase):

2022-09-08T14:46:31,535       def test_something(self):
2022-09-08T14:46:31,535           with IoTDBContainer() as c:
2022-09-08T14:46:31,536               session = Session("localhost", c.get_exposed_port(6667), "root", "root")
2022-09-08T14:46:31,536               session.open(False)
2022-09-08T14:46:31,536               result = session.execute_query_statement("SHOW TIMESERIES")
2022-09-08T14:46:31,537               print(result)
2022-09-08T14:46:31,537               session.close()
2022-09-08T14:46:31,537   ```

2022-09-08T14:46:31,538   by default it will load the image `apache/iotdb:latest`, if you want a specific version just pass it like e.g. `IoTDBContainer("apache/iotdb:0.12.0")` to get version `0.12.0` running.


2022-09-08T14:46:31,539   ## Developers

2022-09-08T14:46:31,539   ### Introduction

2022-09-08T14:46:31,540   This is an example of how to connect to IoTDB with python, using the thrift rpc interfaces. Things are almost the same on Windows or Linux, but pay attention to the difference like path separator.



2022-09-08T14:46:31,541   ### Prerequisites

2022-09-08T14:46:31,542   Python3.7 or later is preferred.

2022-09-08T14:46:31,542   You have to install Thrift (0.11.0 or later) to compile our thrift file into python code. Below is the official tutorial of installation, eventually, you should have a thrift executable.

2022-09-08T14:46:31,543   ```
2022-09-08T14:46:31,543   http://thrift.apache.org/docs/install/
2022-09-08T14:46:31,544   ```

2022-09-08T14:46:31,544   Before starting you need to install `requirements_dev.txt` in your python environment, e.g. by calling
2022-09-08T14:46:31,545   ```shell
2022-09-08T14:46:31,545   pip install -r requirements_dev.txt
2022-09-08T14:46:31,545   ```



2022-09-08T14:46:31,546   ### Compile the thrift library and Debug

2022-09-08T14:46:31,547   In the root of IoTDB's source code folder,  run `mvn clean generate-sources -pl client-py -am`.

2022-09-08T14:46:31,548   This will automatically delete and repopulate the folder `iotdb/thrift` with the generated thrift files.
2022-09-08T14:46:31,548   This folder is ignored from git and should **never be pushed to git!**

2022-09-08T14:46:31,548   **Notice** Do not upload `iotdb/thrift` to the git repo.




2022-09-08T14:46:31,550   ### Session Client & Example

2022-09-08T14:46:31,551   We packed up the Thrift interface in `client-py/src/iotdb/Session.py` (similar with its Java counterpart), also provided an example file `client-py/src/SessionExample.py` of how to use the session module. please read it carefully.


2022-09-08T14:46:31,552   Or, another simple example:

2022-09-08T14:46:31,552   ```python
2022-09-08T14:46:31,553   from iotdb.Session import Session

2022-09-08T14:46:31,553   ip = "127.0.0.1"
2022-09-08T14:46:31,553   port_ = "6667"
2022-09-08T14:46:31,554   username_ = "root"
2022-09-08T14:46:31,554   password_ = "root"
2022-09-08T14:46:31,554   session = Session(ip, port_, username_, password_)
2022-09-08T14:46:31,555   session.open(False)
2022-09-08T14:46:31,555   zone = session.get_time_zone()
2022-09-08T14:46:31,555   session.close()
2022-09-08T14:46:31,555   ```



2022-09-08T14:46:31,557   ### Tests

2022-09-08T14:46:31,557   Please add your custom tests in `tests` folder.

2022-09-08T14:46:31,558   To run all defined tests just type `pytest .` in the root folder.

2022-09-08T14:46:31,558   **Notice** Some tests need docker to be started on your system as a test instance is started in a docker container using [testcontainers](https://testcontainers-python.readthedocs.io/en/latest/index.html).



2022-09-08T14:46:31,560   ### Futher Tools

2022-09-08T14:46:31,560   [black](https://pypi.org/project/black/) and [flake8](https://pypi.org/project/flake8/) are installed for autoformatting and linting.
2022-09-08T14:46:31,561   Both can be run by `black .` or `flake8 .` respectively.



2022-09-08T14:46:31,562   ## Releasing

2022-09-08T14:46:31,562   To do a release just ensure that you have the right set of generated thrift files.
2022-09-08T14:46:31,563   Then run linting and auto-formatting.
2022-09-08T14:46:31,563   Then, ensure that all tests work (via `pytest .`).
2022-09-08T14:46:31,563   Then you are good to go to do a release!



2022-09-08T14:46:31,564   ### Preparing your environment

2022-09-08T14:46:31,565   First, install all necessary dev dependencies via `pip install -r requirements_dev.txt`.



2022-09-08T14:46:31,566   ### Doing the Release

2022-09-08T14:46:31,567   There is a convenient script `release.sh` to do all steps for a release.
2022-09-08T14:46:31,567   Namely, these are

2022-09-08T14:46:31,568   * Remove all transient directories from last release (if exists)
2022-09-08T14:46:31,568   * (Re-)generate all generated sources via mvn
2022-09-08T14:46:31,568   * Run Linting (flake8)
2022-09-08T14:46:31,569   * Run Tests via pytest
2022-09-08T14:46:31,569   * Build
2022-09-08T14:46:31,569   * Release to pypi
