-----------------------------------
Assignee: David Arthur (was: Colin McCabe)
> ProducerId generation should be managed by the Controller
> ---------------------------------------------------------
>
> Key: KAFKA-9154
> URL: https://issues.apache.org/jira/browse/KAFKA-9154
> Project: Kafka
> Issue Type: Sub-task
> Components: core
> Reporter: Viktor Somogyi-Vass
> Assignee: David Arthur
> Priority: Major
>
> Currently producerIds are maintained in Zookeeper but in the future we'd like
> them to be managed by the controller quorum in an internal topic.
> The reason for storing this in Zookeeper was that this must be unique across
> the cluster. In this task it should be refactored such that the
> TransactionManager turns to the Controller for a ProducerId which connects to
> Zookeeper to acquire this ID. Since ZK is the single source of truth and the
> PID won't be cached anywhere it should be safe (just one extra hop added).
