             Summary: Support multiple communication channels between controller participants and spectators
                 Key: HELIX-128
                 URL: https://issues.apache.org/jira/browse/HELIX-128
             Project: Apache Helix
          Issue Type: Bug
            Reporter: kishore gopalakrishna


Currently all communications between controller,participant and spectator happens via zookeeper. This is important for systems where fault tolerance cannot be compromised. But this also increases the latency of communication quite a bit. 

For some applications, it is important that communication between different components is fast, its ok to lose the message in some cases or if controller fails after the message is sent. we can either use tcp or any other pub/sub mechanism to make this as faster.
