InfluxDB v2 Go client library

Use InfluxDB v3 clients

The /api/v2/query API endpoint and associated tooling, such as InfluxDB v2 client libraries and the influx CLI, can’t query an InfluxDB Cloud Dedicated cluster.

InfluxDB v3 client libraries and Flight SQL clients are available that integrate with your code to write and query data stored in InfluxDB Cloud Dedicated.

InfluxDB v3 supports many different tools for writing and querying data. Compare tools you can use to interact with InfluxDB Cloud Dedicated.

Use the InfluxDB Go client library to write data to an InfluxDB Cloud Dedicated database.

This guide presumes some familiarity with Go and InfluxDB. If just getting started, see Get started with InfluxDB.

Before you begin

  1. Install Go 1.13 or later.

  2. Add the client package your to your project dependencies.

    # Add InfluxDB Go client package to your project go.mod
    go get github.com/influxdata/influxdb-client-go/v2
    
  3. Ensure that InfluxDB is running and you can connect to it. For information about what URL to use to connect to your InfluxDB Cloud Dedicated cluster, contact your InfluxData account representative.

Boilerplate for the InfluxDB Go Client Library

Use the Go library to write and query data from InfluxDB.

  1. In your Go program, import the necessary packages and specify the entry point of your executable program.

    package main
    
    import (
        "context"
        "fmt"
        "time"
    
        "github.com/influxdata/influxdb-client-go/v2"
    )
    
  2. Define variables for your InfluxDB database (bucket), organization (required, but ignored), and token.

    bucket := "DATABASE_NAME"
    org := "ignored"
    token := "DATABASE_TOKEN"
    // Store the URL of your InfluxDB instance
    url := "https://cluster-id.influxdb.io"
    
  3. Create the the InfluxDB Go client and pass in the url and token parameters.

    client := influxdb2.NewClient(url, token)
    
  4. Create a write client with the WriteAPIBlocking method and pass in the org and bucket parameters.

    writeAPI := client.WriteAPIBlocking(org, bucket)
    

Write data to InfluxDB with Go

Use the Go library to write data to InfluxDB.

  1. Create a point and write it to InfluxDB using the WritePoint method of the API writer struct.

  2. Close the client to flush all pending writes and finish.

    p := influxdb2.NewPoint("stat",
      map[string]string{"unit": "temperature"},
      map[string]interface{}{"avg": 24.5, "max": 45},
      time.Now())
    writeAPI.WritePoint(context.Background(), p)
    client.Close()
    

Complete example write script

package main

import (
      "context"
      "fmt"
      "time"

      "github.com/influxdata/influxdb-client-go/v2"
)

func main() {
    bucket := "DATABASE_NAME"
    org := "ignored"
    token := "DATABASE_TOKEN"
    // Store the URL of your InfluxDB instance
    url := "https://cluster-id.influxdb.io"
    // Create new client with default option for server url authenticate by token
    client := influxdb2.NewClient(url, token)
    // User blocking write client for writes to desired bucket
    writeAPI := client.WriteAPIBlocking(org, bucket)
    // Create point using full params constructor
    p := influxdb2.NewPoint("stat",
        map[string]string{"unit": "temperature"},
        map[string]interface{}{"avg": 24.5, "max": 45},
        time.Now())
    // Write point immediately
    writeAPI.WritePoint(context.Background(), p)
    // Ensures background processes finishes
    client.Close()
}

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
