[jira] [Created] (ASTERIXDB-2685) Regexp_split implement inside RegExpMatcher class

Hussain Towaileb created ASTERIXDB-2685:
-------------------------------------------

             Summary: Regexp_split implement inside RegExpMatcher class
                 Key: ASTERIXDB-2685
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-2685
             Project: Apache AsterixDB
          Issue Type: Task
            Reporter: Hussain Towaileb


Currently, the regex_split function is using the Java String.split behavior, which compiles the regex with each call, creating an extra object. This could be done inside our RegExpMatcher which re-uses the existing regex part if it's the same, avoiding the creation of a new object sometimes.
