Kafka topic - decrease number of partition

[maciejmaciejko-gid]

What happened?

I created kafka topic's modification request, which decreased partitions number. I tried to approve that request, but it was unsuccessful (Unable to process request. Please contact with administrator). As the result topic was removed from kafka cluster.

Klaw 2.9.0 configured with Aiven (SASL_SSL_SCRAM_MECHANISM_256) - kafka cluster in Azure

Hey @maciejmaciejko-gid thank you for this, were their any logs in the cluster-api that might indicate why the operation failed.

I think when decreasing partitions it has to delete the topic and recreate with less partitions as kafka doesnt support downsizing partitions on topics. so i think it looks like the re-creation with less partitions was the issue.

@maciejmaciejko-gid Like Aindriu mentioned, topic will be deleted and has to be recreated. If re-creation failed, can you share us any logs ?
