Subject Atomic Compare and Swap
Date Sun, 20 Jun 2010 21:42:17 GMT

I was wondering if Cassandra has any plans for supporting atomic compare and swap operation
on a column value? Compare could be on timestamp for the column or the column value itself
and the write of course is on the column value + a new timestamp. If there are no plans on
supporting such an operation, how difficult would it be to implement such a functionality?
I would be interested to start working on this if no one else is doing so and would really
appreciate any pointers in the right direction in how to contribute here.
