[jira] [Created] (KAFKA-6495) Race condition when creating and deleting quickly topics may lead to metrics leak

Mickael Maison created KAFKA-6495:
-------------------------------------

             Summary: Race condition when creating and deleting quickly topics may lead to metrics leak
                 Key: KAFKA-6495
                 URL: https://issues.apache.org/jira/browse/KAFKA-6495
             Project: Kafka
          Issue Type: Bug
            Reporter: Mickael Maison


The issue is described in [https://github.com/apache/kafka/pull/4204]

Once a topic has been created, if it gets deleted when a delayed fetch is in the purgatory, the topic metrics can get recreated.

PR 4204 is a simple workaround that reduces greatly the timing window but does not fix this completely.
