Subject How does checkAndPut guarantee atomicity?
Date Mon, 31 Jan 2011 21:14:38 GMT
It's easy to understand how single-row operations can be atomic, but checkAndPut allows a check
on one row and a put on another while promising this will be atomic.  Is it really guaranteed
to be atomic in that case?  How does that work if the two rows are in different regions (and
possibly different RegionServers)?
