I'd like to verify the behavior of Cassandra under some edge case message loss scenarios.
it's rather difficult to reproduce such things, cuz you have to setup multiple servers, and on each box essentially control the message "gates" to any other nodes in the network. the realistic way that I can think of is to close off all traffic and only manually allow certain messages to pass through. (in the case of Cassandra, we need to let through all gossip messages, and manually control replication messages ) are there some existing simulation frameworks around? junit + various mock frameworks look like a good fit, but in reality is not enough to simulate complex network code, for example, it's basically impossible to setup a simulated N-node cluster on only one test box. Thanks Yang
