Padma Penumarthy created DRILL-5899: ---------------------------------------
Summary: No need to do isAscii check for simple pattern matcher 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
