[jira] [Created] (IMPALA-6412) Memory issues with processing of incoming global runtime filters

Tim Armstrong created IMPALA-6412:
-------------------------------------

             Summary: Memory issues with processing of incoming global runtime filters
                 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
            Assignee: Tim Armstrong


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
