[jira] [Created] (KAFKA-5283) Update clients and server code to make sure that epoch and sequence numbers wrap around

Apurva Mehta created KAFKA-5283:
-----------------------------------

             Summary: Update clients and server code to make sure that epoch and sequence numbers wrap around
                 Key: KAFKA-5283
                 URL: https://issues.apache.org/jira/browse/KAFKA-5283
             Project: Kafka
          Issue Type: Sub-task
            Reporter: Apurva Mehta
            Priority: Blocker
             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.
