Yin Xiang updated SCB-277:
--------------------------
Summary: [pack] concurrent event processing issue (was: [pack] persist
index of last processed event to avoid concurrency and re-processing issue)
> [pack] concurrent event processing issue
> ----------------------------------------
>
> Key: SCB-277
> URL: https://issues.apache.org/jira/browse/SCB-277
> Project: Apache ServiceComb
> Issue Type: Improvement
> Components: Saga
> Reporter: Yin Xiang
> Assignee: Yin Xiang
> Priority: Major
>
> currently, when alpha is down, it starts from the first event till the last
> on restart.
> multiple alphas may process the same event at the same time, which results in
> concurrent update errors when persisting events as commands. it may not
> affect correctness, but does leave warning logs.
> persisting last processed event index can help solve the problems above.
