Subject [jira] Updated: (DERBY-1257) Enhance Derby optimizer and execution model to support effective use of multiple indexes on one table. Derby currently can use one index on a table and there are many situations where using multiple indexes on a table could improve performance significant

Kathey Marsden updated DERBY-1257:
----------------------------------

    Fix Version/s: 10.3.0.0
                       (was: 10.2.0.0)

Since this remains unassigned I don't think it reasonable to think someone will pick it up
and fix it for 10.2.  Looks like a high value fix for 10.3 though.
Changing to 10.3
