        Installation
        ------------
        .. marker-install-start
        
        InfluxDB python library uses `RxPY <https://github.com/ReactiveX/RxPY>`__ - The Reactive Extensions for Python (RxPY).
        
        **Python 3.6** or later is required.
        
        .. note::
        
            It is recommended to use ``ciso8601`` with client for parsing dates. ``ciso8601`` is much faster than built-in Python datetime. Since it's written as a ``C`` module the best way is build it from sources:
        
            **Windows**:
        
            You have to install `Visual C++ Build Tools 2015 <http://go.microsoft.com/fwlink/?LinkId=691126&fixForIE=.exe>`_ to build ``ciso8601`` by ``pip``.
        
            **conda**:
        
            Install from sources: ``conda install -c conda-forge/label/cf202003 ciso8601``.
        
        pip install
        ^^^^^^^^^^^
        
        The python package is hosted on `PyPI <https://pypi.org/project/influxdb-client/>`_, you can install latest version directly:
        
        .. code-block:: sh
        
           pip install influxdb-client[ciso]
        
        Then import the package:
        
        .. code-block:: python
        
           import influxdb_client
        
        Setuptools
        ^^^^^^^^^^
        
        Install via `Setuptools <http://pypi.python.org/pypi/setuptools>`_.
        
        .. code-block:: sh
        
           python setup.py install --user
        
        (or ``sudo python setup.py install`` to install the package for all users)
        
        .. marker-install-end
        
        Getting Started
        ---------------
        
        Please follow the `Installation`_ and then run the following:
        
        .. marker-query-start
        
        .. code-block:: python
        
           from influxdb_client import InfluxDBClient, Point
           from influxdb_client.client.write_api import SYNCHRONOUS
        
           bucket = "my-bucket"
        
           client = InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org")
        
           write_api = client.write_api(write_options=SYNCHRONOUS)
           query_api = client.query_api()
        
           p = Point("my_measurement").tag("location", "Prague").field("temperature", 25.3)
        
           write_api.write(bucket=bucket, record=p)
        
           ## using Table structure
           tables = query_api.query('from(bucket:"my-bucket") |> range(start: -10m)')
        
           for table in tables:
               print(table)
               for row in table.records:
                   print (row.values)
        
        
           ## using csv library
           csv_result = query_api.query_csv('from(bucket:"my-bucket") |> range(start: -10m)')
           val_count = 0
           for row in csv_result:
               for cell in row:
                   val_count += 1
        
        
        .. marker-query-end
        
        Client configuration
        --------------------
        
        Via File
        ^^^^^^^^
        A client can be configured via ``*.ini`` file in segment ``influx2``.
        
        The following options are supported:
        
        - ``url`` - the url to connect to InfluxDB
        - ``org`` - default destination organization for writes and queries
        - ``token`` - the token to use for the authorization
        - ``timeout`` - socket timeout in ms (default value is 10000)
        - ``verify_ssl`` - set this to false to skip verifying SSL certificate when calling API from https server
        - ``ssl_ca_cert`` - set this to customize the certificate file to verify the peer
        
        .. code-block:: python
        
            self.client = InfluxDBClient.from_config_file("config.ini")
        
        .. code-block::
        
            [influx2]
            url=http://localhost:8086
            org=my-org
            token=my-token
            timeout=6000
            verify_ssl=False
        
        Via Environment Properties
        ^^^^^^^^^^^^^^^^^^^^^^^^^^
        A client can be configured via environment properties.
        
        Supported properties are:
        
        - ``INFLUXDB_V2_URL`` - the url to connect to InfluxDB
        - ``INFLUXDB_V2_ORG`` - default destination organization for writes and queries
        - ``INFLUXDB_V2_TOKEN`` - the token to use for the authorization
        - ``INFLUXDB_V2_TIMEOUT`` - socket timeout in ms (default value is 10000)
        - ``INFLUXDB_V2_VERIFY_SSL`` - set this to false to skip verifying SSL certificate when calling API from https server
        - ``INFLUXDB_V2_SSL_CA_CERT`` - set this to customize the certificate file to verify the peer
        
        .. code-block:: python
        
            self.client = InfluxDBClient.from_env_properties()
        
        .. marker-index-end
        
        
        How to use
        ----------
        
        Writes
        ^^^^^^
        .. marker-writes-start
        
        The `WriteApi <https://github.com/influxdata/influxdb-client-python/blob/master/influxdb_client/client/write_api.py>`_ supports synchronous, asynchronous and batching writes into InfluxDB 2.0.
        The data should be passed as a `InfluxDB Line Protocol <https://docs.influxdata.com/influxdb/latest/write_protocols/line_protocol_tutorial/>`_\ , `Data Point <https://github.com/influxdata/influxdb-client-python/blob/master/influxdb_client/client/write/point.py>`_ or Observable stream.
        
        **Important: The WriteApi in batching mode (default mode) is suppose to run as a singleton. To flush all your data you should call ``_write_client.close()`` at the end of your script.**
        
        *The default instance of WriteApi use batching.*
        
        The data could be written as
        """"""""""""""""""""""""""""
        
        1. ``string`` or ``bytes`` that is formatted as a InfluxDB's line protocol
        2. `Data Point <https://github.com/influxdata/influxdb-client-python/blob/master/influxdb_client/client/write/point.py#L16>`__ structure
        3. Dictionary style mapping with keys: ``measurement``, ``tags``, ``fields`` and ``time``
        4. List of above items
        5. A ``batching`` type of write also supports an ``Observable`` that produce one of an above item
        6. `Pandas DataFrame <https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html>`_
        
        
        Batching
        """"""""
        
        .. marker-batching-start
        
        The batching is configurable by ``write_options``\ :
        
        .. list-table::
           :header-rows: 1
        
           * - Property
             - Description
             - Default Value
           * - **batch_size**
             - the number of data pointx to collect in a batch
             - ``1000``
           * - **flush_interval**
             - the number of milliseconds before the batch is written
             - ``1000``
           * - **jitter_interval**
             - the number of milliseconds to increase the batch flush interval by a random amount
             - ``0``
           * - **retry_interval**
             - the number of milliseconds to retry unsuccessful write. The retry interval is used when the InfluxDB server does not specify "Retry-After" header.
             - ``5000``
           * - **max_retries**
             - the number of max retries when write fails
             - ``3``
           * - **max_retry_delay**
             - the maximum delay between each retry attempt in milliseconds
             - ``180_000``
           * - **exponential_base**
             - the base for the exponential retry delay, the next delay is computed as ``retry_interval * exponential_base^(attempts-1) + random(jitter_interval)``
             - ``5``

        """""""""""""""""""""""""
        The following example demonstrate a simplest way how to write and query date with the InfluxDB Cloud.
        
        At first point you should create an authentication token as is described `here <https://v2.docs.influxdata.com/v2.0/security/tokens/create-token/>`_.
        
        After that you should configure properties: ``influx_cloud_url``, ``influx_cloud_token``, ``bucket`` and ``org`` in a ``influx_cloud.py`` example.
        
        The last step is run a python script via: ``python3 influx_cloud.py``.

        Advanced Usage
        --------------
        
        Gzip support
        ^^^^^^^^^^^^
        .. marker-gzip-start
        
        ``InfluxDBClient`` does not enable gzip compression for http requests by default. If you want to enable gzip to reduce transfer data's size, you can call:
        
        .. code-block:: python
        
           from influxdb_client import InfluxDBClient
        
           _db_client = InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org", enable_gzip=True)
        
        .. marker-gzip-end
        
        Delete data
        ^^^^^^^^^^^
        .. marker-delete-start
        
        The `delete_api.py <influxdb_client/client/delete_api.py>`_ supports deletes `points <https://v2.docs.influxdata.com/v2.0/reference/glossary/#point>`_ from an InfluxDB bucket.

        InfluxDB 1.8 API compatibility
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        
        `InfluxDB 1.8.0 introduced forward compatibility APIs <https://docs.influxdata.com/influxdb/v1.8/tools/api/#influxdb-2-0-api-compatibility-endpoints>`_ for InfluxDB 2.0. This allow you to easily move from InfluxDB 1.x to InfluxDB 2.0 Cloud or open source.
        
        The following forward compatible APIs are available:
        
        =======================================================  ====================================================================================================  =======
         API                                                     Endpoint                                                                                              Description
        =======================================================  ====================================================================================================  =======

        For detail info see `InfluxDB 1.8 example <examples/influxdb_18_example.py>`_.
        
        HTTP Retry Strategy
        ^^^^^^^^^^^^^^^^^^^
        By default the client uses a retry strategy only for batching writes (for more info see `Batching`_).
        For other HTTP requests there is no one retry strategy, but it could be configured by ``retries``
        parameter of ``InfluxDBClient``.
        
        For more info about how configure HTTP retry see details in `urllib3 documentation <https://urllib3.readthedocs.io/en/latest/reference/index.html?highlight=retry#urllib3.Retry>`_.
        
        .. code-block:: python
        
            from urllib3 import Retry
        
            from influxdb_client import InfluxDBClient
        
            retries = Retry(connect=5, read=2, redirect=5)
            client = InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org", retries=retries)
        
        Nanosecond precision
        ^^^^^^^^^^^^^^^^^^^^
        
        The Python's `datetime <https://docs.python.org/3/library/datetime.html>`_ doesn't support precision with nanoseconds
        so the library during writes and queries ignores everything after microseconds.
        
        If you would like to use ``datetime`` with nanosecond precision you should use
        `pandas.Timestamp <https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Timestamp.html#pandas.Timestamp>`_
        that is replacement for python ``datetime.datetime`` object and also you should set a proper ``DateTimeHelper`` to the client.
        
        * sources - `nanosecond_precision.py <https://github.com/influxdata/influxdb-client-python/blob/master/examples/nanosecond_precision.py>`_
