> Key: KAFKA-5283
> URL: https://issues.apache.org/jira/browse/KAFKA-5283
> Project: Kafka
> Issue Type: Sub-task
> Components: clients, core, producer
> Reporter: Apurva Mehta
> Assignee: Jason Gustafson
> Priority: Blocker
> Labels: exactly-once
> Fix For: 0.11.0.0
>
>
> The design doc mentions that the epoch and sequence numbers will wrap around.
> However, the current client and server code (on the producer, in the
> `ProducerIdMapping` class, in the transaction coordinator) does not do this.
> Once all the pieces are in place we should go through and make sure that the
> handling of sequence numbers and epoch is consistent across the board. Would
> be good to add a system or integration test for this as well, if possible.
