Tim Armstrong resolved IMPALA-1276.
-----------------------------------
Resolution: Won't Fix
We have this enabled for ORC and Kudu, and I don't think it is that important
for other file formats that are already less performant.
> Enable probe filter optimization for scanner other than parquet-scanners
> ------------------------------------------------------------------------
>
> Key: IMPALA-1276
> URL: https://issues.apache.org/jira/browse/IMPALA-1276
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 1.4.1
> Reporter: Ippokratis Pandis
> Assignee: Henry Robinson
> Priority: Minor
> Labels: performance
>
> The probe filter optimization is enabled only on joins on tables whose
> majority is parquet. The reason being that only hdfs-parquet-scanner can take
> advantage of it.
> It would be good to enable this optimization for all the other scanners.
> From the build side there is no need to do any change.
