--------------------------------
Summary: Eliminate splits based on SARGs using stripe statistics
in ORC
Key: HIVE-5632
URL: https://issues.apache.org/jira/browse/HIVE-5632
Project: Hive
Issue Type: Improvement
Affects Versions: 0.13.0
Reporter: Prasanth J
Assignee: Prasanth J
HIVE-5562 provides stripe level statistics in ORC. Stripe level statistics
combined with predicate pushdown in ORC (HIVE-4246) can be used to eliminate
the stripes (thereby splits) that doesn't satisfy the predicate condition. This
can greatly reduce unnecessary reads.
