If you use thrift API= , you have to maintain lot of low level code by yourself which is already b= eing polished by HLC=A0 hector, pycassa also with HLC your can easily switc= h between thrift and growing CQL.

You might consider using a higher level client (like= Hector indeed). If you don't want this you will have to write your own= connection pool. For start take a look at Hector. But keep in mind that yo= u might be reinventing=A0the wheel.

I am using Thrift API and= I am not able to find anything on the internet about how to configure it for multiple nodes. I am not using any proper client like Hector.

Hi there,

=A0

When you speak to one node it will internally redire= ct the request to the proper node (local / external): but you won't be = able to failover on a crash of the localhost.

For adding another node to the connection pool you s= hould take a look at the documentation of your java client.

Good luck!
