Clara Xiong updated HBASE-15181:
--------------------------------
Description:
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

Perfect fit for the use cases that:

data.
2. never or rarely deletes data.
Out-of-order writes are handled gracefully so the data will still get to the
right store file for time-range-scan and re-compacton with existing store file
in the same time window is handled by ExploringCompactionPolicy.

impact is minimized.
