[jira] [Commented] (SPARK-10915) Add support for UDAFs in Python

    [ https://issues.apache.org/jira/browse/SPARK-10915?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15058987#comment-15058987 ] 

Tristan commented on SPARK-10915:
---------------------------------

Would the analogy to UDAF support in Python be lambdas, as mentioned in the description? Or is this more appropriate an abstract base class? From the Scala example, it seems the most direct implementation would follow the same interface.
