InfluxDB OSS v2

Replicate data from InfluxDB OSS

Use InfluxDB replication streams (InfluxDB Edge Data Replication) to replicate the incoming data of select buckets to one or more buckets on a remote InfluxDB OSS, InfluxDB Cloud, or InfluxDB Enterprise instance.

Replicate data from InfluxDB OSS to InfluxDB Cloud, InfluxDB OSS, or InfluxDB Enterprise.

Configure a replication stream

Use the influx CLI or the InfluxDB 2.7 API to configure a replication stream.

To replicate data to InfluxDB OSS or InfluxDB Enterprise, adjust the remote connection values accordingly.

CLI API

  1. Send a POST request to your local InfluxDB OSS /api/v2/remotes endpoint to create a remote connection to replicate data to.

    POST localhost:8086/api/v2/remotes

    Include the following in your request:

    • Request method: POST
    • Headers:
      • Authorization: Token scheme with your local InfluxDB OSS API token
      • Content-type: application/json
    • Request body: JSON object with the following fields:
      * Required
      • * allowInsecureTLS: All insecure TLS connections
      • description: Remote description
      • * name: Remote connection name
      • * orgID: local InfluxDB OSS organization ID
      • * remoteAPIToken: Remote InfluxDB API token (API token must have write access to the target bucket)
      • * remoteOrgID: Remote InfluxDB organization ID
      • * remoteURL: Remote InfluxDB instance URL
    curl --request POST http://localhost:8086/api/v2/remotes \
  --header 'Authorization: Token INFLUX_OSS_TOKEN' \
  --data '{
    "allowInsecureTLS": false,
    "description": "Example remote description",
    "name": "Example remote name",
    "orgID": "INFLUX_OSS_ORG_ID",
    "remoteAPIToken": "REMOTE_INFLUX_TOKEN",
    "remoteOrgID": "REMOTE_INFLUX_ORG_ID",
    "remoteURL": "https://cloud2.influxdata.com"
  }'

    If you already have remote InfluxDB connections configured, you can use an existing connection. To view existing connections, use the /api/v2/remotes endpoint with the GET request method.

    GET localhost:8086/api/v2/remotes

    Include the following in your request:

    • Request method: GET
    • Headers:

    • Query parameters:
      • orgID: Local InfluxDB OSS organization ID
    curl --request GET \
  http://localhost:8086/api/v2/remotes?orgID=INFLUX_OSS_ORG_ID \
  --header 'Authorization: Token INFLUX_OSS_TOKEN' \

  2. Send a POST request to your local InfluxDB OSS /api/v2/replications endpoint to create a replication stream.

    POST localhost:8086/api/v2/remotes
    • Copy
    • Fill window

    Include the following in your request:

    • Request method: POST
    • Headers:
      • Authorization: Token scheme with your local InfluxDB OSS API token
      • Content-type: application/json
    • Request body: JSON object with the following fields: * Required
      • dropNonRetryableData: Drop data when a non-retryable error is encountered.
      • * localBucketID: Local InfluxDB OSS bucket ID to replicate writes from.
      • * maxAgeSeconds: Maximum age of data in seconds before it is dropped (default is 604800, must be greater than or equal to 0).
      • * maxQueueSizeBytes: Maximum replication queue size in bytes (default is 67108860, must be greater than or equal to 33554430).
      • * name: Replication stream name.
      • * orgID: Local InfluxDB OSS organization ID.
      • * remoteBucketID: Remote bucket ID to replicate writes to.
      • * remoteBucketName: Remote bucket name to replicate writes to. If replicating to InfluxDB Enterprise, use the db-name/rp-name bucket name syntax.
      • * remoteID: Remote connection ID

remoteBucketID and remoteBucketName are mutually exclusive. If replicating to InfluxDB Enterprise, use remoteBucketName with the db-name/rp-name bucket name syntax.

curl --request POST http://localhost:8086/api/v2/replications \
  --header 'Authorization: Token INFLUX_OSS_TOKEN' \
  --data '{
    "dropNonRetryableData": false,
    "localBucketID": "INFLUX_OSS_BUCKET_ID",
    "maxAgeSeconds": 604800,
    "maxQueueSizeBytes": 67108860,
    "name": "Example replication stream name",
    "orgID": "INFLUX_OSS_ORG_ID",
    "remoteBucketName": "REMOTE_INFLUX_BUCKET_NAME",
    "remoteID": "REMOTE_ID",
  }'
  • Copy
  • Fill window

Once a replication stream is created, InfluxDB OSS will replicate all writes from the specified local bucket to the remote InfluxDB bucket. To get information such as the current queue size, max queue size, and latest status code for each replication stream, send a GET request to your local InfluxDB OSS /api/v2/replications endpoint.

GET localhost:8086/api/v2/replications

Include the following in your request:

  • Request method: GET
  • Headers:
    • Authorization: Token scheme with your local InfluxDB OSS API token
  • Query parameters:
    • orgID: Local InfluxDB OSS organization ID
curl --request GET \
  http://localhost:8086/api/v2/replications?orgID=INFLUX_OSS_ORG_ID \
  --header 'Authorization: Token INFLUX_OSS_TOKEN' \

Important things to note

  • Only write operations are replicated. Other data operations (like deletes or restores) are not replicated.
  • In InfluxDB OSS, large write request bodies are written entirely. When replicated, write requests are sent to the remote bucket in batches. The maximum batch size is 500 kB (typically between 250 to 500 lines of line protocol). This may result in scenarios where some batches succeed and others fail.

Replicate downsampled or processed data

In some cases, you may not want to write raw, high-precision data to a remote InfluxDB instance. To replicate only downsampled or processed data:

  1. Create a bucket in your InfluxDB OSS instance to store downsampled or processed data in.

  2. Create an InfluxDB task that downsamples or processes data and stores it in the new bucket. For example:

    import "influxdata/influxdb/tasks"
import "types"

// omit this line if adding task via the UI
option task = {name: "Downsample raw data", every: 10m}

data = () => from(bucket: "example-bucket")
    |> range(start: tasks.lastSuccess(orTime: -task.every))

numeric = data()
    |> filter(fn: (r) => types.isType(v: r._value, type: "float") or types.isType(v: r._value, type: "int") or types.isType(v: r._value, type: "uint"))
    |> aggregateWindow(every: task.every, fn: mean)

nonNumeric = data()
    |> filter(fn: (r) => types.isType(v: r._value, type: "string") or types.isType(v: r._value, type: "bool"))
    |> aggregateWindow(every: task.every, fn: last)

union(tables: [numeric, nonNumeric])
    |> to(bucket: "example-downsampled-bucket")

  3. Create a replication stream to replicate data from the downsampled bucket to the remote InfluxDB instance.

View InfluxDB OSS replication service metrics

In addition to replication stream information that you can access using the CLI or API, you can view replication service-level metrics for your InfluxDB OSS instance, such as /api/v2/write error details, the number and duration of calls to the service, and the total number of points queued.

To view replication service-level metrics send a GET request to your local InfluxDB OSS /metrics endpoint.

InfluxDB 3 Core and Enterprise are now in Beta

InfluxDB 3 Core and Enterprise are now available for beta testing, available under MIT or Apache 2 license.

InfluxDB 3 Core is a high-speed, recent-data engine that collects and processes data in real-time, while persisting it to local disk or object storage. InfluxDB 3 Enterprise is a commercial product that builds on Core’s foundation, adding high availability, read replicas, enhanced security, and data compaction for faster queries. A free tier of InfluxDB 3 Enterprise will also be available for at-home, non-commercial use for hobbyists to get the full historical time series database set of capabilities.
