Well it depends on what you need and want. I didn't mean the round robin thing because that part is really not very hard to make or understand. Hector uses a smart one that tries to connect to other servers if it timeout and other things. But with Hector as a whole I think you get so much features it is hard to understand how it works, so I prefer using the thrift API myself and learn as I go on and then I don't need any high level API anymore. /J

The hosts are symmetric so any host will do. There are also higher lever libraries that help with that as well as connection pooling and other goodies On Mon, Aug 16, 2010 at 1:14 PM, Ying Tang <ivytang0...@gmail.com<mailto:ivytang0...@gmail.com>> wrote: After reading the docs and the thrift demo , i found that if the demo ,if we want to connect to the database , we must first do "TTransport tr = new TSocket("localhost", 9160) " . Then we operate on the database through this TTransport . But this operation assigns a fixed IP , so all requests would transformed to this IP . And the cassandra node of this ip would load a heavy reading load and proxy load . Do i understand this wrong , or cassandra client has other way to access cassandra and doesn't need to assign a fixed IP? -- Best regards, Ivy Tang -- Best regards, Ivy Tang -- Best regards, Ivy Tang -- Best regards, Ivy Tang
