-------------------------------------------
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.
