Class DateTieredCompactionPolicy


@LimitedPrivate("Configuration") public class DateTieredCompactionPolicy extends SortedCompactionPolicy
HBASE-15181 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 data write and scan and a focus on the most recent 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 or overridden at per-table or per-column-family level by hbase shell.
