Subject [jira] Commented: (PIG-928) UDFs in scripting languages
Date Fri, 16 Oct 2009 23:39:31 GMT

    [ https://issues.apache.org/jira/browse/PIG-928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12766774#action_12766774

Ashutosh Chauhan commented on PIG-928:
--------------------------------------

Right, I overlooked it. I think Ruby and Python are two most widely used scripting languages
and both are supported by BSF. So, comparing BSF with direct bindings:
1) Performance : Initial test shows almost equal.
2) Support of multiple languages.
3) Ease of implementation 
To me, BSF seems to be the way to go for this, atleast the first-cut. Implementing this feature
using BSF will allow us to expose this to users quickly and if many people are using it and
finding one particular language to be slow then we can explore language bindings for that
particular language. Thoughts?

> It should be possible to write UDFs in scripting languages such as python, ruby, etc.
 This frees users from needing to compile Java, generate a jar, etc.  It also opens Pig to
programmers who prefer scripting languages over Java.
