> Rewrite BETWEEN to IN for integer types for stats estimation
> ------------------------------------------------------------
>
> Key: HIVE-20432
> URL: https://issues.apache.org/jira/browse/HIVE-20432
> Project: Hive
> Issue Type: Improvement
> Affects Versions: 4.0.0
> Reporter: Vineet Garg
> Assignee: Vineet Garg
> Priority: Major
> Attachments: HIVE-20432.1.patch, HIVE-20432.2.patch

>
> IN clause provides better statistics estimation since predicates are equality
> based and it keeps into account selectivity of all values. BETWEEN is
> rewritten into {{>= AND <=}} i.e. non-equality predicates which cause worse
> estimation. For integer types BETWEEN could be rewritten into IN e.g. BETWEEN
> 4 and 7 is equivalent to IN (4,5,6,7).
