[GitHub] [helix] xyuanlu opened a new issue #1361: Move ST message to state validation from executing phase to scheduling phase.
xyuanlu opened a new issue #1361:
URL: https://github.com/apache/helix/issues/1361
Currently we do all the state validation (the from state should be same current state and to state should be different to current state) for state transition message when the message is being executed in HelixStateTransitionHandler.
We should move the to state validation to the scheduling stage because of the following reasons:
1. it is a no-op operation, thus we should not create a thread to execute it.
2.The lag between scheduling and executing could add additional latency for controller and eventually application latency.
