Matthias J. Sax resolved KAFKA-5510.
------------------------------------
Resolution: Won't Do
> Streams should commit all offsets regularly
> -------------------------------------------
>
> Key: KAFKA-5510
> URL: https://issues.apache.org/jira/browse/KAFKA-5510
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Reporter: Matthias J. Sax
> Priority: Major
>
> Currently, Streams commits only offsets of partitions it did process records
> for. Thus, if a partition does not have any data for longer then
> {{offsets.retention.minutes}} (default 1 day) the latest committed offset
> get's lost. On failure or restart {{auto.offset.rese}} kicks in potentially
> resulting in reprocessing old data.
> Thus, Streams should commit _all_ offset on a regular basis. Not sure what
> the overhead of a commit is -- if it's too expensive to commit all offsets on
> regular commit, we could also have a second config that specifies an
> "commit.all.interval".
> This relates to https://issues.apache.org/jira/browse/KAFKA-3806, so we
> should sync to get a solid overall solution.
> At the same time, it might be better to change the semantics of
> {{offsets.retention.minutes}} in the first place. It might be better to apply
> this setting only if the consumer group is completely dead (and not on "last
> commit" and "per partition" basis). Thus, this JIRA would be a workaround fix
> if core cannot be changed quickly enough.
