> UDFLike: reduce Regex NFA sizes
> -------------------------------
>
> Key: HIVE-13196
> URL: https://issues.apache.org/jira/browse/HIVE-13196
> Project: Hive
> Issue Type: Improvement
> Components: UDF
> Affects Versions: 1.3.0, 1.2.1, 2.0.0, 2.1.0
> Reporter: Gopal V
> Assignee: Gopal V
> Priority: Minor
> Attachments: HIVE-13196.1.patch
>
>
> The NFAs built from complex regexes in UDFLike are extremely complex and
> spend a lot of time doing simple expression matching with no backtracking.
> Prevent NFA -> DFA explosion by using reluctant regex matches instead of
> greedy matches.
