Subject About atomic compare-and-swap
Date Fri, 05 Jul 2013 10:48:46 GMT

I have been working on the implementation of compare-and-swap (cas) at
the client level on top of Cassandra. The result of my work is available
on It is a small python library which
contains a few atomic concurrent objects, including cas, and which uses
an off-the-shelf Cassandra implementation.

The approach I have taken is explained in a paper located in the bib
directory. Roughly speaking, the idea is to implement only
obstruction-free objects to sidestep the consensus/CAP impossibility result.

I hope this might interest you.
