Subject [jira] Updated: (HIVE-1803) Implement bitmap indexing in Hive
Date Wed, 16 Feb 2011 03:06:57 GMT

Marquis Wang updated HIVE-1803:
-------------------------------

    Attachment: HIVE-1803.3.patch

New patch that includes tests and fixes problems John mentioned.

Bitmap UDFs are "hidden" by giving them leading underscores, since we do need to expose them
for using the index for now. When we get automatic usage working, we can hide them more effectively.
