Subject [jira] [Commented] (ACCUMULO-3191) Use JONI regex library to speed up operations
Date Wed, 01 Oct 2014 18:19:33 GMT


Josh Elser commented on ACCUMULO-3191:

Cool stuff. Copy'ing the description from HBASE-11907 because I had never heard of JONI before:

The joni regex engine (, a Java port of Oniguruma regexp library
done by the JRuby project, is:

* MIT licensed
* Designed to work with byte[] arguments instead of String
* Capable of handling UTF8 encoding
* Regex syntax compatible
* Interruptible
* About twice as fast as j.u.regex
* Has JRuby's jcodings library as a dependency, also MIT licensed

> We could use the JONI library in things like the RegexIterator, because it's dealing
with byte arrays natively already. We should investigate the benefit and see if we can get
a speedup.
