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.
