unable to set topic configuration

[rumwei]

• redpanda console version: v2.3.1
• kafka cluster version: 2.0.1 in redpanda console's topics configuration config page: http://host:8080/topics/topic?p=-1&s=50&o=-1#configuration, we want to set topic's retention.ms to 4days from 3days, the response is

Failed to edit topic config: failed to request alter configs: broker is too old; the broker has already indicated it will not know how to handle the request","error":"failed to edit topic config: failed to request alter configs: broker is too old; the broker has already indicated it will not know how to handle the request

It means kafka cluster's version is too low? What's the lowest kafka cluster version supported? Where can i get the compatibility?

Thanks for any response!

Hey @rumwei , Console uses the IncrementalAlterConfigs API, which was added in Apache Kafka v2.3.0. We should indeed check for the API compatibility in Console and reflect this in the UI accordingly. I'll leave this issue open until this is done.
