Labels: resource-management scalability (was: resource-management)
> Memory issues with processing of incoming global runtime filters on
> coordinator
> -------------------------------------------------------------------------------
>
> Key: IMPALA-6412
> URL: https://issues.apache.org/jira/browse/IMPALA-6412
> Project: IMPALA
> Issue Type: Bug
> Components: Backend, Distributed Exec
> Affects Versions: Impala 2.11.0
> Reporter: Tim Armstrong
> Priority: Major
> Labels: resource-management, scalability
>
> This is a tracking JIRA for runtime filter memory issues that occur when
> processing global runtime filters, which is currently done entirely on the
> coordinator. I'll link all related issues that I know about and we can close
> this issue once we're fully satisfied that the problem is resolved.
> Currently the known issues include:
> * All filters are processed on the coordinator, which quickly becomes a
> bottleneck
> * We don't track the memory consumed by thrift strings in incoming RPCs
