----------------------------------
Resolution: Fixed
Hadoop Flags: Reviewed
Status: Resolved (was: Patch Available)
Resolving this, since it seems to be committed. Thanks, Clara Xiong for the
work.
We would still be interested in the IO numbers, and getting some documentation
for this feature if possible.

> This is a simple implementation of date-based tiered compaction similar to
> Cassandra's for the following benefits:
> 1. Improve date-range-based scan by structuring store files in date-based
> tiered layout.
> 2. Reduce compaction overhead.
> 3. Improve TTL efficiency.
> Perfect fit for the use cases that:
> 1. has mostly date-based date write and scan and a focus on the most recent
> data.
> 2. never or rarely deletes data.
> Out-of-order writes are handled gracefully. Time range overlapping among
> store files is tolerated and the performance impact is minimized.
> Configuration can be set at hbase-site.xml or overriden at per-table or
> per-column-famly level by hbase shell.
> Design spec is at
