Subject [jira] [Commented] (FLINK-4017) [py] Add Aggregation support to Python API
Date Tue, 07 Jun 2016 15:37:20 GMT

    [ https://issues.apache.org/jira/browse/FLINK-4017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15318695#comment-15318695

Chesnay Schepler commented on FLINK-4017:

when using the python API data always exists as a byte array on the java side. 

you will either have to 
* implement the aggregation on the python side
* apply a deserializationMap, groupBy, aggregate, and serializationMap on the java side.
