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?
