Summary: Pluggable standby tasks assignor for Kafka Streams
Key: KAFKA-10686
URL: https://issues.apache.org/jira/browse/KAFKA-10686
Project: Kafka
Issue Type: Improvement
Components: streams
Reporter: Levani Kokhreidze
In production, Kafka Streams instances often run across different clusters and
availability zones. In order to guarantee high availability of the Kafka
Streams deployments, users would need more granular control over which on
instances standby tasks can be created.
Idea of this ticket is to expose interface for Kafka Streams which can be
implemented by users to control where standby tasks can be created.
Kafka Streams can have RackAware assignment as a default implementation that
will take into account `rack.id` of the application and make sure that standby
tasks are created on different racks.
Point of this ticket though is to more flexibility to users on standby task
creation, in cases where just rack awareness is not enough.
