Summary: Vectorization: Add ChainedCheckerFactory for LIKE
Key: HIVE-13204
URL: https://issues.apache.org/jira/browse/HIVE-13204
Project: Hive
Issue Type: Improvement
Components: Vectorization
Affects Versions: 2.1.0
Reporter: Gopal V
Assignee: Gopal V
Currently, Vectorization runs through a UTF-8 decode to produce a String & then
check for mildly complex patterns like "http://%.exe"; using a Regex.
Since this pattern doesn't need any backtracking patterns, using a full fledged
Regex is too expensive.
