> 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
