--------------------------------------
Summary: assorted ORC refactorings for LLAP on trunk
Key: HIVE-9555
URL: https://issues.apache.org/jira/browse/HIVE-9555
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
Assignee: Sergey Shelukhin
To minimize conflicts and given that ORC is being developed rapidly on trunk, I
would like to refactor some parts of ORC "in advance" based on the changes in
LLAP branch. Mostly it concerns making parts of ORC code (esp. SARG, but also
some internal methods) more modular and easier to use from alternative
codepaths. There's also significant change to how data reading is handled -
BufferChunk inherits from DiskRange; the reader receives a list of DiskRange-s
(as before), but instead of making a list of buffer chunks it replaces ranges
with buffer chunks in the original (linked) list.
