Subject [jira] [Updated] (HIVE-9439) merge ORC disk ranges as we go when reading RGs
Date Wed, 21 Jan 2015 22:33:34 GMT

Sergey Shelukhin updated HIVE-9439:
-----------------------------------
    Attachment: HIVE-9439.patch

Attaching the patch. We expect subsequent RGs to be close... not sure if it makes sense to
populate and check lastRange between different streams; would the be expected to be close
together?

> Currently we get ranges for all the RGs individually, then merge them. We can do some
(probably most of) the merging as we go.
