>
> Currently merge join implementation in pig includes construction of an index
> on sorted data and use of that index to seek into the "right input" to
> efficiently perform the join operation. Some loaders (notably the zebra
> loader) internally implement an index on sorted data and can perform this
> seek efficiently using their index. So the use of the index needs to be
> abstracted in such a way that when the loader supports indexing, pig uses it
> (indirectly through the loader) and does not construct an index.
