-----------------------------------------
Ping. Since 1.3 was postponed several times due to various issue, curious if there's any update on that?

> 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 https://docs.google.com/document/d/1_AmlNb2N8Us1xICsTeGDLKIqL6T-oHoRLZ323MG_uy8/edit?usp=sharing
> Results in our production is at https://docs.google.com/document/d/1GqRtQZMMkTEWOijZc8UCTqhACNmdxBSjtAQSYIWsmGU/edit#
