> KAFKA-14561 wrote code that assumed that if a transactional ID was included, all record batches were transactional and had the same producer ID.
> This work with improve validation and fix the code that assumes all batches are transactional.
> Further, KAFKA-14561 will not assume all records are transactional.
> Originally this ticket had an action item to ensure all the producer IDs are the same in the batches since we send a single txn ID, but that can be done in a followup KAFKA-14958, as we still need to assess if we can enforce this without breaking workloads.
