Nick Dimiduk commented on PHOENIX-2646:
---------------------------------------
The workflow around jars deployed to {{hbase.dynamic.jars.dir}}, how multiple
versions are handled during upgrade, etc. sounds fragile. There's no way to
unload a UDF from RS loaded classes short of restarting the daemon. Looks like
a source of bugs to me. I'll want to understand a workflow around hygienically
deploying and maintaining UDFs, but I'm not there yet.

> We already support {{REGEXP}} functions for string manipulation. Let's add
> full regex matching support as well. For example, Postgres has the {{~}}
> operator for [POSIX regular expression
> matching|http://www.postgresql.org/docs/9.3/static/functions-matching.html#FUNCTIONS-POSIX-REGEXP].
