----------------------------------
Summary: JRuby UDFs should have a more efficient implementation
Key: PIG-4648
URL: https://issues.apache.org/jira/browse/PIG-4648
Project: Pig
Issue Type: New Feature
Reporter: Brian Johnson
Priority: Minor
The current jruby UDF implementation translates all the Java objects to ruby
objects and back. This makes it very simple for ruby programmers, but it is
very inefficient. I propose a second jruby implementation that passes through
the Java objects to avoid this extra overhead. It should be able to re-use a
lot of the existing code. The existing implementation is under
org.apache.pig.scripting.jruby. I propose that the new implementation go under
org.apache.pig.scripting.jruby.native and will be referenced with "using
jruby-native". This is meant to reference "native" pig classes. I realize it
could be confused with the Java native interface, but I couldn't think of a
better name.
