Problem Statement

When trying to create a topic on the Redpanda Serverless cluster, you may receive the following message;

POLICY_VIOLATION: maximum number of partitions exceeded (100)

This is because the serverless cluster limits up to 100 logical partitions. (Ref: Doc) 

Solution

Deleting unnecessary topics will give a space to create a new topic.
You can check the current total number of partitions you created by rpk topic list .
Here is an example of how to calculate the total number quickly.

$ rpk topic list
NAME   PARTITIONS  REPLICAS
tp001  10          3
tp002  50          3
tp003  30          3
$ rpk topic list  | grep -v NAME | awk '{total+=$2} END {print total}'
90

Please contact Support if you need to increase the limits.

Note

The logical partition is the total number of partitions of topics. This does not count replicas.
