Description
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.
