[jira] [Commented] (HBASE-11907) Use the joni byte[] regex engine in place of j.u.regex in RegexStringComparator

["Andrew Purtell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-11907?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14147211#comment-14147211 ] 

Andrew Purtell commented on HBASE-11907:
----------------------------------------

This is ready to go. Other uses of j.u.regex in HBase code deal with strings already, e.g. paths, configuration. One place we might use it is in HTD/HCD attribute parsing but it's not worth it.

> The joni regex engine (https://github.com/jruby/joni), 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
