Subject [jira] Commented: (PIG-365) Map side optimization for Limit (top k case)
Date Wed, 18 Aug 2010 19:48:18 GMT

    [ https://issues.apache.org/jira/browse/PIG-365?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12899990#action_12899990

Mridul Muralidharan commented on PIG-365:
-----------------------------------------

collecting only top k per mapper is obviously flawed : unless there are other constraints
not mentioned here (or I misunderstood the bug).
