-----------------------------------
Sounds good to me.
> Offset default behavior for streams

> Introduce a systems.<system name>.streams.<stream name>.samza.offset.default
> configuration, which specifies what to do when no checkpoint exists for an
> input topic. This is a similar to setting to Kafka's auto.offset.reset
> setting. Developers will be able to specify "oldest", "latest", or "fail".
> we should also add the ability to override offsets for specific stream
> partitions. Something like:
> {noformat}
> systems.<system name>.streams.<stream
> name>.samza.force.offsets=0:123,1:123,2:123
> {noformat}
> The format I'm proposing is:
> {noformat}
> <partition string>:<force offset>,...
> {noformat}
> This is obviously dependent on offsets not having ':' or ',' in them, which I
> think is a safe assumption.
> This setting would force the system consumer to be registered with the
> specified offset for the given SSP (ignoring both the checkpoint, if it
> exists, and the samza.reset.offset setting).
