> 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 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.
> Time range overlapping among store files is tolerated and the performance impact is minimized.
