orthogonal means 90 degrees. Two lines are orthogonal if the cross at 90 degrees. Two ideas are orthogonal means that they are not compatible. Transactions is orthogonal with Cassandra's design means that it will require a lot of work and trade-off to implement transactions into Cassandra. Is

No, it just means they don't have dependencies on each other. In this case, it means you could create a transactional layer on top of cassandra, without having to make it part of the core. Now I Understand, thank you. On Sun, Apr 25, 2010 at 12:46 AM, Jonathan Ellis jbel...@gmail.com wrote:

Is this something that also needs to be managed in Java? In most examples I've seen, connections are created like this: TSocket socket = new TSocket(location, thriftport) TBinaryProtocol binaryProtocol = new TBinaryProtocol(socket, false, false);

Yes, one should use either the TBufferedTransport or TFramedTransport in Java for performance reasons. These are analogous to the C# Socket classes and you should see a performance improvement from buffering. On Apr 24, 2010, at 5:31 PM, Joost Ouwerkerk jo...@openplaces.org wrote: Is
