Constructor Detail

RegionReplicationSink

public RegionReplicationSink(org.apache.hadoop.conf.Configuration conf,
                             RegionInfo primary,
                             TableDescriptor td,
                             RegionReplicationBufferManager manager,
                             Runnable flushRequester,
                             AsyncClusterConnection conn)

Method Detail

add

public void add(WALKeyImpl key,
                WALEdit edit,
                ServerCall<?> rpcCall)

Add this edit to replication queue.

The rpcCall is for retaining the cells if the edit is built within an rpc call and the rpc call has cell scanner, which is off heap.

stop

public void stop()

Stop the replication sink.

Usually this should only be called when you want to close a region.

waitUntilStopped

public void waitUntilStopped()
                      throws InterruptedException

Make sure that we have finished all the replicating requests.

After returning, we can make sure there will be no new replicating requests to secondary replicas.

This is used to keep the replicating order the same with the WAL edit order when writing.

Throws:

InterruptedException
