[jira] [Commented] (PIG-1804) Alow Jython function to implement Algebraic and/or Accumulator interfaces

["Mathias Herberts (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-1804?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13149624#comment-13149624 ] 

Mathias Herberts commented on PIG-1804:
---------------------------------------

The Algebraic interface has three methods which return class names to be fed to FuncSpec.

This approach pretty much forbids dynamically created Algebraic UDFs using pure (with no compilation phase) scripting languages (not only Jython, but Groovy, JavaScript are also concerned).

What would the impact be if Algebraic was refactored so get{Initial,Intermed,Final} return class instances instead of class names?

> Currently Python UDFs can only be simple functions. For performance improvements in advanced use cases it should be possible to extend Algebraic and/or Accumulator interfaces
