> 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
> Assignee: Vaibhav Gumashta
> Priority: Major
>
> 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.
