This project implements an ExtendedRegexStringComparator for HBase that has additional RegEx engines.

The default upstream HBase version includes two:

• JAVA
• JONI

This projects implements a few more:

• RE2J
• BRICS
  • Uses Automaton
• FAST_BRICS
  • Uses RunAutomaton with tableize set to false
• FASTEST_BRICS
  • Uses RunAutomaton with tableize set to true

Please note that all of them support slightly different syntaxes.

Please note that the brics / Automaton one works differently than the others. The others use find() on Pattern to find substrings. As far as I can tell Automaton does not support this so the regex needs to match the whole string!

You can build the project using Maven:

mvn clean package

The resulting JAR file needs to be deployed in the HBase classpath.

This is completely untested. Use at your own risk!
