Subject [jira] Commented: (PIG-1090) Update sources to reflect recent changes in load-store interfaces
Date Wed, 23 Dec 2009 05:05:29 GMT

    [ https://issues.apache.org/jira/browse/PIG-1090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12793927#action_12793927
] 

Dmitriy V. Ryaboy commented on PIG-1090:
----------------------------------------

I think LoadMetadata should not be responsible for pushing down filters. This is something
LoadPushdown is for.  LoadMetadata is, according to the redesign proposal, an interface for
loading metadata, not using it to guide processing. 

The filter pushdown optimization seems like a fairly involved piece of code. Can we break
this out into a separate ticket, to separate the issue of fulfilling the redesign from the
issue of implementing this optimization?
