Hey Guys,
      Any one used ZK for Database sharding? I am thinking something like this-
-DB shard info is kept in ZK
-Application makes the call to ZK first to get the shard info (which database 
server has what data)
-Then application connects to right DB for accessing data.
-Any shard change is communicated to the app with ZK watch.

I see that Rackspace use case  and just checking the community for anyone done 
it...

Thanks,
-Uday.
