Subject [jira] [Updated] (FLINK-1240) We cannot use sortGroup on a global reduce
Date Thu, 13 Nov 2014 09:32:33 GMT

     [ https://issues.apache.org/jira/browse/FLINK-1240?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aljoscha Krettek updated FLINK-1240:
------------------------------------
    Description: 
This is only an API problem, I hope.

I also know, that this is potentially a very bad idea because everything must be sorted on
one node. In some cases, such as sorted first-n this would make sense, though, since there
we use a combiner.

I also know, that this is potentially a very bad idea because everything must be sorted on
one node. In some cases, such as sorted first(n) this would make sense, though, since there
