Subject Why only check1-and-putMany and check1-and-deleteMany?
Date Sun, 18 Nov 2012 03:30:19 GMT
If I understand correctly, an HTable has two composite atomic operations, 
checkAndPut and checkAndDelete.  The check part checks just a single 
column's value.  Why not allow checking more than one column?

Why no checkAndAppend?

The checkAndPut operation can put to multiple columns, right?  And the 
checkAndDelete operation can delete multiple columns, right?  Why not let 
them be mixed?  Why not checkAndMutate?
