--------------------------------------
Summary: store end offset of compressed data for RG in RowIndex in
ORC
Key: HIVE-9660
URL: https://issues.apache.org/jira/browse/HIVE-9660
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
Right now the end offset is estimated, which in some cases results in tons of
extra data being read.
We can add a separate array to RowIndex (positions_v2?) that stores number of
compressed buffers for each RG, or end offset, or something, to remove this
estimation magic
