Jason Gustafson updated KAFKA-5017:
-----------------------------------
Assignee: Jason Gustafson
Status: Patch Available (was: Open)
> Consider making baseOffset the first offset in message format v2
> ----------------------------------------------------------------
>
> Key: KAFKA-5017
> URL: https://issues.apache.org/jira/browse/KAFKA-5017
> Project: Kafka
> Issue Type: Sub-task
> Components: clients, core, producer
> Reporter: Ismael Juma
> Assignee: Jason Gustafson
> Fix For: 0.11.0.0
>
>
> Currently baseOffset starts as the first offset of the batch. If the first
> record is removed by compaction, baseOffset doesn't change and it is no
> longer the same as the first offset of the batch. This is inconsistent with
> every other field in the record batch header and it seems like there is no
> longer a reason for this behaviour.
> We should consider simplifying the behaviour so that baseOffset is simply the
> first offset of the record batch. We need to do this before 0.11 or we
> probably won't be able to do it until the next message format version change.
