Subject [jira] [Updated] (FLINK-6091) Implement and turn on the retraction for aggregates
Date Fri, 07 Apr 2017 15:29:41 GMT

     [ https://issues.apache.org/jira/browse/FLINK-6091?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hequn Cheng updated FLINK-6091:
-------------------------------
    Description: 
Implement functions for generating and consuming retract messages for different aggregates.

1. add delete/add property to Row
2. implement functions for generating retract messages for unbounded groupBy
3. implement functions for handling retract messages for different aggregates.

  was:Implement the functions for processing retract message for grouping window aggregate.
No retract generating function needed as for now, as the current grouping window aggregates
are all executed at “without early firing mode”.
