---------------------------------------
Summary: Avoid state restore via rebalance if standbys are enabled
Key: KAFKA-13501
URL: https://issues.apache.org/jira/browse/KAFKA-13501
Project: Kafka
Issue Type: Improvement
Components: streams
Reporter: Matthias J. Sax
There are certain scenario in which Kafka Streams wipes out local state and
rebuilt it from scratch. This is a thread local cleanup, ie, no rebalance is
triggered, and we end up with an offline task until state restoration finished.
If standby tasks are enable, it might actually make sense to trigger a
rebalance instead, to get the task re-assigned to the instance hosting the
standby so get the task active again quickly.
