Stephan Ewen commented on FLINK-1138: ------------------------------------- Should we close this with "wont't fix"? There have been no requests, it is fairly low priority, and very tricky... > Allow users to specify methods instead of fields in key expressions > ------------------------------------------------------------------- > > Key: FLINK-1138 > URL: https://issues.apache.org/jira/browse/FLINK-1138 > Project: Flink > Issue Type: Improvement > Components: Java API > Reporter: Robert Metzger > Priority: Minor > > Currently, users can specify grouping fields only on the fields of a POJO. > It would be nice to allow users also to name a method (such as > "getVertexId()") to be called. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
