Tim Armstrong resolved IMPALA-967.
----------------------------------
Resolution: Won't Fix
This is kinda open ended. We fixed a bunch of perf issues in this area so I'll
close for now.
> Investigate wide table performance
> ----------------------------------
>
> Key: IMPALA-967
> URL: https://issues.apache.org/jira/browse/IMPALA-967
> Project: IMPALA
> Issue Type: Improvement
> Components: Perf Investigation
> Affects Versions: Impala 1.3
> Reporter: Skye Wanderman-Milne
> Priority: Minor
> Labels: codegen
>
> Querying wide tables (very roughly 1000+ columns) is very slow. It looks like
> the time is spent in planning and/or codegen, and that the time increases
> worse than linearly with the number of columns.
