Christian Schneider updated SLING-11914:
----------------------------------------
Summary: Accept initial offset via OffsetMessage (was: Accept initial
offset via PingMessage)
> Accept initial offset via OffsetMessage
> ---------------------------------------
>
> Key: SLING-11914
> URL: https://issues.apache.org/jira/browse/SLING-11914
> Project: Sling
> Issue Type: Improvement
> Components: Content Distribution
> Reporter: Christian Schneider
> Assignee: Christian Schneider
> Priority: Major
>
> When DistributionSubscriber does not yet have a stored offset it is in a
> problematic state.
> When a package message is sent and DistributionSubscriber starts late or
> restarts it might miss the message.
> This issue aim to improve the situation by accepting offsets via ping
> messages. The messaging provider can send such a message immediately when the
> poller is created to inform subscriber about the current offset on the topic.
> This offset is then written to repository.
> From this point in time the timing problem is solved. No message after the
> stored offset can be lost.
