--------------------------------
Summary: Limit the number of records per batch in
GroupCoordinatorShard#cleanupGroupMetadata
Key: KAFKA-15587
URL: https://issues.apache.org/jira/browse/KAFKA-15587
Project: Kafka
Issue Type: Task
Reporter: Jeff Kim
The existing group/offset expiration may generate an unbounded number of
records. This also applies to the new coordinator
([https://github.com/apache/kafka/pull/14467).|https://github.com/apache/kafka/pull/14467)]
We should limit the number of records per batch. One caveat is that other API
results assume their records are appended atomically, so we need to keep this
in mind if we implement the change in CoordinatorPartitionWriter#append.
