Avoid Cassandra forwarding request to other nodes: - Use consistency level ONE; - Create data model to do single request with single key, since different keys may belong to different nodes and requires forwarding requests to them; - Use smart client to calculate token for key and select appropriate node (primary or replica) by token range; - Turn off Dynamic Snitch (it may forward request to other replica even it has the data); - Have all or hot data in page cache (no HDD disk IO) or use SSD; - If you do regular updates to key, do not use row cache, otherwise you may try.
