[jira] [Created] (TAJO-193) Add string pattern matching operators

Hyunsik Choi created TAJO-193:

             Summary: Add string pattern matching operators
                 Key: TAJO-193
                 URL: https://issues.apache.org/jira/browse/TAJO-193
             Project: Tajo
          Issue Type: New Feature
          Components: physical operator, planner/optimizer
            Reporter: Hyunsik Choi
            Assignee: Hyunsik Choi
             Fix For: 0.2-incubating


This patch adds some pattern matching operators, such as ILIKE, SIMILAR TO, REGEX operators, and improves LIKE operator. In addition, it improves null handling on those string pattern matching operators.

Also, I've added the manual to the query language wiki page (https://wiki.apache.org/tajo/QueryLanguage#PatternMatching).
