[jira] [Created] (KAFKA-19674) [3.9] Disallow create too many partitions in ZK mode

Edoardo Comar created KAFKA-19674:
-------------------------------------

             Summary: [3.9] Disallow create too many partitions in ZK mode
                 Key: KAFKA-19674
                 URL: https://issues.apache.org/jira/browse/KAFKA-19674
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 3.9.1, 3.9.0, 3.8.1, 3.8.0
            Reporter: Edoardo Comar


Also when running in Zookeeper mode Kafka can go OOM if an attempt is made to create a topic with too many partitions, or to extend a topic with too many partitions.

I think it is worth to port also the constrain introduded in KRaft mode to the 3.9 version of Kafka.
