Subject [jira] [Commented] (FLINK-2237) Add hash-based Aggregation
Date Sat, 30 Jan 2016 07:31:39 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2237?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15124790#comment-15124790

ASF GitHub Bot commented on FLINK-2237:

Github user mbalassi commented on the pull request:

    I think exposing the feature through the API similarly to the way join strategies are
exposed is the way to properly make this feature available for users. I would leave the well-tested
sorting version the default for now.
