Srivignesh created KAFKA-16398:
----------------------------------
Summary: mirror-maker2 running into OOM while filtering high
number of messages
Key: KAFKA-16398
URL: https://issues.apache.org/jira/browse/KAFKA-16398
Project: Kafka
Issue Type: Bug
Components: connect, mirrormaker
Affects Versions: 3.6.1
Reporter: Srivignesh
Based on custom predicate, our application is filtering messages during
mirroring.
When the HasHeader:test method of the predicate returns false (when it has to
drop messages from mirroring), it encounters below exceptions.
However when it returns true (the messages are forwarded for mirroring), it
works fine without OOM.
Note: This issue doesn't occur in version 2.8.0.
