Subject [jira] Commented: (PIG-1209) Port POJoinPackage to proactively spill
Date Fri, 29 Jan 2010 21:53:34 GMT

    [ https://issues.apache.org/jira/browse/PIG-1209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12806525#action_12806525
] 

Pradeep Kamath commented on PIG-1209:
-------------------------------------

For testing, the data for the first input of the join can be a large number of records (so
that size in memory > 500 MB or so) with the same join key. This will hopefully spill and
fail with old code and not fail with new code.

> POPackage proactively spills the bag whereas POJoinPackage still uses the SpillableMemoryManager.
We should port this to use InternalCacheBag which proactively spills.
