> Better topic assignment algorithm
> ---------------------------------
>
> Key: BOOKKEEPER-508
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-508
> Project: Bookkeeper
> Issue Type: Sub-task
> Components: hedwig-server
> Reporter: Sijie Guo
> Attachments: topicassignment.pdf
>
>
> currently each hub server just cached its owned topics. for those they don't
> owned topics, hub server has to request metadata store to know the topic
> owner.
> the bad thing is that clients access hub server thru VIP which is
> round-robin, which means there would be lots of missed accessing owner,
> causing lots of traffic to metadata store.
> need to provide a better algorithm to avoid unnecessary metadata traffic.
