Subject Re: Does anybody work about transaction on cassandra ?
Date Thu, 22 Apr 2010 14:14:07 GMT
No, as far as I know no one is working on transaction support in Cassandra.
Transactions are orthogonal to the design of Cassandra[1][2], although a
system could be designed incorporating Cassandra and other elements a la
Google's MegaStore[3] to support transactions.  Google uses Paxos, one might
be able to use Zookeeper[4] to design such a system, but it would be a
daunting task.
