Usecase: DB Sharding
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.

This might be of some help:
http://wiki.apache.org/solr/ZooKeeperIntegration
I am not sure if Solr/Lucene has the implementation part done or thats just the design doc.
Also,
http://katta.sourceforge.net/documentation/how-katta-works
thanks

We define all database information in xml files and put them into zookeeper
with protocol buffers format.
The clients get some configurations which using by business and build
datasource dynamically.
Also the clients watch the node in zookeeper and rebuild datasource while
the necessary node has changed.
