Subject Re: Adding new nodes
Date Fri, 05 Feb 2010 05:36:51 GMT
Sorry I guess I was not clear enough. While the existing data is being moved
do requests for reads go to the new nodes? If so what if that data has not
yet migrated? There is no problem for writes. But how is the routing for the
reads handled in this situation?

Cheers
