---------------------------------------
Summary: ACID: explore how we can avoid a move step during
compaction
Key: HIVE-21164
URL: https://issues.apache.org/jira/browse/HIVE-21164
Project: Hive
Issue Type: Bug
Components: Transactions
Affects Versions: 3.1.1
Reporter: Vaibhav Gumashta
Currently, we write compacted data to a temporary location and then move the
files to a final location, which is an expensive operation on some cloud file
systems. Since HIVE-20823 is already in, it can control the visibility of
compacted data for the readers. Therefore, we can perhaps avoid writing data to
a temporary location and directly write compacted data to the intended final
path.
