Syed S. Albiz updated HIVE-2036:
--------------------------------
Attachment: HIVE-2036.3.patch
This patch is still WIP, there are a couple of issues I know still need
correcting. In particular, the index_auto_unused.q testcase fails, since I
updated the partition predicates to propagate properly, there was no check to
make sure that the index was built on the partition being queried (but the
testcase would still pass since partition predicates weren't propagated anyway)
I probably also want to refactor the logic in IndexWhereProcessor before this
is ready.
> Update bitmap indexes for automatic usage

> HIVE-1644 will provide automatic usage of indexes, and HIVE-1803 adds bitmap
> index support. The bitmap code will need to be extended after it is
> committed to enable automatic use of indexing. Most work will be focused in
> the BitmapIndexHandler, which needs to generate the re-entrant QL index
> query. There may also be significant work in the IndexPredicateAnalyzer to
> support predicates with OR's, instead of just AND's as it is currently.
