Ivan Kelly commented on BOOKKEEPER-154:
---------------------------------------
Yes, i don't think the server should automatically GC messages as it breaks the
guarantees that Hedwig gives. However, it is acceptable to provide an API to do
this, as it may be something which the application requires. I think it would
be best to put it into a HedwigAdmin client. I think Ben was talking about
writing one. See his message on the mailing list on December 19th.
> Garbage collect messages for those subscribers inactive/offline for a long
> time.

> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-154
> Project: Bookkeeper
> Issue Type: New Feature
> Components: hedwig-client, hedwig-server
> Affects Versions: 4.0.0
> Reporter: Sijie Guo
>
> Currently hedwig tracks subscribers progress for garbage collecting published
> messages. If subscriber subscribe and becomes offline without unsubscribing
> for a long time, those messages published in its topic have no chance to be
> garbage collected.
> A time based garbage collection policy would be suitable for this case.
