Subject [jira] [Commented] (HIVE-2354) Support automatic rebuilding of indexes when they go stale
Date Fri, 19 Aug 2011 19:34:27 GMT


Syed S. Albiz commented on HIVE-2354:

Actually, looking more closely at the testcase output, there is an issue with this patch.
The timestamps set when the index is rebuilt are still coming up stale, so we don't see index
usage in the EXPLAIN plan of the SELECT query. I will investigate further

> Support a mode where indexes will be automatically rebuilt when the table/partition they
are based on is modified. So if index foo is built on table bar, and bar has it's contents
overwritten, we should support a mode where index foo will automatically rebuild itself.
