Michael Smith updated IMPALA-13534:
-----------------------------------
Description: For joins, we create runtime filters that are sent from the
build side to the probe side to do some early filtering of results of a scan.
With shared CTEs, the consumers may not receive the same runtime filters, so we
can't forward them all the way to the scans, but we should be able to apply
them to the CTE consumer results. Implement support for connecting runtime
filters to CTE consumers. (was: Add planner support for generating CTE
producer fragments, removing sequence in distributed plan. CTE buffer must
remain active until all consumers have finished reading.)
