org.apache.hadoop.hbase.regionserver.compactions.RowKeyDateTieringValueProvider

All Implemented Interfaces:

CustomTieredCompactor.TieringValueProvider

@Private
public class RowKeyDateTieringValueProvider
extends Object
implements CustomTieredCompactor.TieringValueProvider

Provides a tiering value for compactions by extracting and parsing a date from the row key. This implementation uses a configurable regex and date format to locate and parse a date substring from the row key and returns the parsed epoch time in milliseconds. Configuration properties can be set at globally or at table level.
