Russell Melick updated HIVE-1644:
---------------------------------
Attachment: HIVE-1644.11.patch
* I don't think that my method of relabeling the tasks works correctly
(renumberTasks(...) in Task.java). It also seems like the labels do not affect
the run-time execution.
* I haven't had a chance to write a unit test that uses partitions on an
index, so I haven't really looked at how the code will perform
(IndexWhereProcessor:66). I'm not really sure how indexes change once there are
partitions. Is index_compact_2.q a reasonable starting place for a partitioned
index test?
* Using the TS%FIL instead of FIL%SEL seems to work nicely, as it gives easy
access to the table scan operator.
* I created the followup HIVE-2081 ticket for #3 from above.
> use filter pushdown for automatically accessing indexes

> HIVE-1226 provides utilities for analyzing filters which have been pushed
> down to a table scan. The next step is to use these for selecting available
> indexes and generating access plans for those indexes.
