Troubleshoot issues writing data

Limited availability

InfluxDB Clustered is currently only available to a limited group of InfluxData customers. If interested in being part of the limited access group, please contact the InfluxData Sales team.

Learn how to avoid unexpected results and recover from errors when writing to InfluxDB Clustered.

Handle write responses

In InfluxDB Clustered, writes are synchronous. After InfluxDB validates the request and ingests the data, it sends a success response (HTTP 204 status code) as an acknowledgement that the data is written and queryable. To ensure that InfluxDB handles writes in the order you request them, wait for the acknowledgement before you send the next request.

If InfluxDB successfully writes all the request data to the database, it returns success (HTTP 204 status code). The first rejected point in a batch causes InfluxDB to reject the entire batch and respond with an HTTP error status.

Review HTTP status codes

InfluxDB uses conventional HTTP status codes to indicate the success or failure of a request. The message property of the response body may contain additional details about the error. Write requests return the following status codes:

HTTP response code Message Description
204 "Success" If InfluxDB ingested the data
400 "Bad request" message contains the first malformed line If data is malformed
401 "Unauthorized" If the Authorization header is missing or malformed or if the token doesn’t have permission to write to the database. See examples using credentials in write requests.
404 "Not found" requested resource type (for example, “organization” or “database”), and resource name If a requested resource (for example, organization or database) wasn’t found
500 "Internal server error" Default status for an error
503 “Service unavailable” If the server is temporarily unavailable to accept writes. The Retry-After header describes when to try the write again.

If your data did not write to the database, see how to troubleshoot rejected points.

Troubleshoot failures

If you notice data is missing in your database, do the following:

Troubleshoot rejected points

InfluxDB rejects points that fall within the same partition (default partitioning is measurement and day) as existing bucket data and have a different data type for an existing field.

Check for field data type differences between the rejected data point and points within the same database and partition–for example, did you attempt to write string data to an int field?

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.
