> Key: DRILL-5899
> URL: https://issues.apache.org/jira/browse/DRILL-5899
> Project: Apache Drill
> Issue Type: Improvement
> Components: Execution - Flow
> Reporter: Padma Penumarthy
> Assignee: Padma Penumarthy
> Priority: Critical
>
> For simple pattern matcher, we do not have to do isAscii check.
> UTF-8 encoding ensures that no UTF-8 character is a prefix of any other valid
> character. So, for the 4 simple patterns we have i.e. startsWith, endsWith,
> contains and constant, we can get rid of this check. This will help improve
> performance.
