> Slow compilation due to IN to OR transformation

> Project: Hive
> Issue Type: Improvement
> Components: Logical Optimizer
> Reporter: Vineet Garg
> Assignee: Vineet Garg
> Priority: Major
> Labels: pull-request-available
> Attachments: HIVE-22074.1.patch, HIVE-22074.2.patch,

>
> Currently Hive transform IN expressions to OR to apply various CBO rules.
> This incur significant performance hit if IN consist of large number of
> expressions.
> It is better to not transform IN expressions to OR in such cases because
> overall benefit of various optimizations/transformations is unrealized due to
> the compilation overhead
