Brian Johnson commented on PIG-4380:
------------------------------------
I don't think it should be replaced because the new version will not be
backwards compatible
> Jruby only UDFs

> Key: PIG-4380
> URL: https://issues.apache.org/jira/browse/PIG-4380
> Project: Pig
> Issue Type: New Feature
> Affects Versions: 0.15.0
> Reporter: Brian Johnson
>
> The current ruby UDF implementation does a lot of conversion from java types
> to native ruby types. While this makes it easy to write and test UDFs in
> plain ruby without any Pig dependencies, the performance leaves something to
> be desired. There should be a jruby-specific implementation that uses the
> java types without conversion.
