Subject [jira] Commented: (PIG-1062) load-store-redesign branch: change SampleLoader and subclasses to work with new LoadFunc interface
Date Tue, 17 Nov 2009 20:56:39 GMT

    [ https://issues.apache.org/jira/browse/PIG-1062?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12779126#action_12779126
] 

Thejas M Nair commented on PIG-1062:
------------------------------------

Yes, I think SampleLoader.getNext()  can be moved to RandomSampleLoader(). Any new class that
needs to use random sample implementation, can subclass RandomSampleLoader instead of SampleLoader.

> This is part of the effort to implement new load store interfaces as laid out in http://wiki.apache.org/pig/LoadStoreRedesignProposal
.
> PigStorage and BinStorage are now working.
> SampleLoader and subclasses -RandomSampleLoader, PoissonSampleLoader need to be changed
to work with new LoadFunc interface.  
> Fixing SampleLoader and RandomSampleLoader will get order-by queries working.
> PoissonSampleLoader is used by skew join.
