[jira] [Resolved] (IMPALA-1276) Enable probe filter optimization for scanner other than parquet-scanners

["Tim Armstrong (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IMPALA-1276?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.

>             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.
