Class ReplicationSink

java.lang.Object
  org.apache.hadoop.hbase.replication.regionserver.ReplicationSink

public class ReplicationSink
extends java.lang.Object

This class is responsible for replicating the edits coming from another cluster.

This replication process is currently waiting for the edits to be applied before the method can return. This means that the replication of edits is synchronized (after reading from HLogs in ReplicationSource) and that a single region server cannot receive edits from two sources at the same time

This class uses the native HBase client in order to replicate entries.

TODO make this class more like ReplicationSource wrt log handling
