> Participant duplicated state transition handling rework
> -------------------------------------------------------
>                 Key: HELIX-705
>                 URL: https://issues.apache.org/jira/browse/HELIX-705
>             Project: Apache Helix
>          Issue Type: Task
>            Reporter: Hao Zhang
>            Priority: Major
> Helix should have some re-work on participant side message handling:
>  - Duplicated message in same batch: discard the later one
>  - Duplicated message in different batches, the later one should be discarded if the
first one is in progress
>  - During state transition, we should not rely on current state delta to get partition's
current state, but should lock on state model def (thread safety)
>  - Duplicated state transition (toState == currentState) should not result in error,
which is confusion, but should report success
