Class MajorCompactorTTL

java.lang.Object

org.apache.hadoop.conf.Configured

org.apache.hadoop.hbase.util.compaction.MajorCompactor

org.apache.hadoop.hbase.util.compaction.MajorCompactorTTL

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, org.apache.hadoop.util.Tool

Direct Known Subclasses:

RSGroupMajorCompactionTTL

@InterfaceAudience.LimitedPrivate(value="Tools")
public class MajorCompactorTTL
extends MajorCompactor

This tool compacts a table's regions that are beyond it's TTL. It helps to save disk space and regions become empty as a result of compaction.
