> Key: IMPALA-5384
> URL: https://issues.apache.org/jira/browse/IMPALA-5384
> Project: IMPALA
> Issue Type: Improvement
> Affects Versions: Impala 2.9.0
> Reporter: Marcel Kornacker
> Assignee: Dan Hecht
> Priority: Major
>
> The coordinator has a central lock (lock_) which is used very liberally to
> synchronize state changes that don't need to be synchronized, creating a
> concurrency bottleneck.
> Also, the coordinator contains a number of data structures related to INSERT
> finalization that don't need to be part of and synchronized with the rest of
> the coordinator state.
