InfluxDB client libraries

This page documents an earlier version of InfluxDB. InfluxDB v2.6 is the latest stable version. See the equivalent InfluxDB v2.6 documentation: Use InfluxDB client libraries.

InfluxDB client libraries are language-specific packages that integrate with the InfluxDB 2.0 API and support both InfluxDB 1.8+ and InfluxDB 2.0.

Note: We recommend using the new client libraries on this page to leverage the new read (via Flux) and write APIs and prepare for conversion to InfluxDB 2.0 and InfluxDB Cloud. For more information, see InfluxDB 2.0 API compatibility endpoints. Client libraries for InfluxDB 1.7 and earlier may continue to work, but are not maintained by InfluxData.

Client libraries

Functionality varies between client libraries. Refer to client libraries on GitHub for specifics regarding each client library.

Install and use a client library

To install and use the Python client library, follow the instructions below. To install and use other client libraries, refer to the client library documentation for detail.

Install and use the Python client library

  1. Install the Python client library.

    pip install influxdb-client
    
  2. Ensure that InfluxDB is running. If running InfluxDB locally, visit http://localhost:8086. (If using InfluxDB Cloud, visit the URL of your InfluxDB Cloud UI.)

  3. In your program, import the client library and use it to write data to InfluxDB. For example:

    import influxdb_client
    from influxdb_client.client.write_api import SYNCHRONOUS
    
  4. Define your database and token variables, and create a client and writer object. The InfluxDBClient object takes 2 parameters: url and token

    database = "<my-db>"
    token = "<my-token>"
    client = influxdb_client.InfluxDBClient(
    url="http://localhost:8086",
    token=token,
    

    Note: The database (and retention policy, if applicable) are converted to a [bucket](https://v2. docs.influxdata.com/v2.0/reference/glossary/#bucket) data store compatible with InfluxDB 2.0.

  5. Instantiate a writer object using the client object and the write_api method. Use the write_api method to configure the writer object.

    client = influxdb_client.InfluxDBClient(url=url, token=token)
    write_api = client.write_api(write_options=SYNCHRONOUS)
    
  6. Create a point object and write it to InfluxDB using the write method of the API writer object. The write method requires three parameters: database, (optional) retention policy, and record.

    p = influxdb_client.Point("my_measurement").tag("location", "Prague").field("temperature", 25.3)
    write_api.write(database:rp, record=p)

InfluxDB Cloud backed by InfluxDB IOx

All InfluxDB Cloud organizations created on or after January 31, 2023 are backed by the new InfluxDB IOx storage engine. Check the right column of your InfluxDB Cloud organization homepage to see which InfluxDB storage engine you’re using.

If powered by IOx, this is the correct documentation.

If powered by TSM, see the TSM-based InfluxDB Cloud documentation.

InfluxDB Cloud backed by InfluxDB TSM

All InfluxDB Cloud organizations created on or after January 31, 2023 are backed by the new InfluxDB IOx storage engine which enables nearly unlimited series cardinality and SQL query support. Check the right column of your InfluxDB Cloud organization homepage to see which InfluxDB storage engine you’re using.

If powered by TSM, this is the correct documentation.

If powered by IOx, see the IOx-based InfluxDB Cloud documentation.

State of the InfluxDB Cloud (IOx) documentation

The new documentation for InfluxDB Cloud backed by InfluxDB IOx is a work in progress. We are adding new information and content almost daily. Thank you for your patience!
