org.apache.tephra.hbase.txprune.PruneUpperBoundWriter

All Implemented Interfaces:

com.google.common.util.concurrent.Service

public class PruneUpperBoundWriter
extends com.google.common.util.concurrent.AbstractIdleService

Thread that will write the the prune upper bound. An instance of this class should be obtained only through PruneUpperBoundWriterSupplier which will also handle the lifecycle of this instance.
