DateTieredCompactionPolicy
HBASE-15181 This is a simple implementation of date-based tiered compaction similar to
Cassandra's for the following benefits:
Improve date-range-based scan by structuring store files in date-based tiered layout.
Reduce compaction overhead.
Improve TTL efficiency.
Perfect fit for the use cases that:
has mostly date-based data write and scan and a focus on the most recent data.
Out-of-order writes are handled gracefully.
