Luís Ferreira commented on CASSANDRA-2686:
------------------------------------------
I've taken your advice and used Cages for the Read and Write locks. From this I
constructed a Transaction system on top of Cassandra. As soon as I have some
performance test results I'll put them here, as well as the code, if anyone is
interested.
It basically implements a write ahead log, taking advantage of the atomicity in
per row updates, and of idempotent updates. It also has a pre processing
mechanism for transactions that do not know à priori the columns they will use
(when using indexes, for example).
