类 MultiRowMutationEndpoint

java.lang.Object

org.apache.hadoop.hbase.protobuf.generated.MultiRowMutationProtos.MultiRowMutationService

org.apache.hadoop.hbase.coprocessor.MultiRowMutationEndpoint

所有已实现的接口:

com.google.protobuf.Service, Coprocessor, RegionCoprocessor

@InterfaceAudience.LimitedPrivate(value="Coprocesssor")
 @InterfaceStability.Evolving
public class MultiRowMutationEndpoint
extends org.apache.hadoop.hbase.protobuf.generated.MultiRowMutationProtos.MultiRowMutationService
implements RegionCoprocessor

This class demonstrates how to implement atomic multi row transactions using HRegion.mutateRowsWithLocks(Collection, Collection, long, long) and Coprocessor endpoints. Defines a protocol to perform multi row transactions. See MultiRowMutationEndpoint for the implementation.
See HRegion.mutateRowsWithLocks(Collection, Collection, long, long) for details and limitations.
Example: List<Mutation> mutations = ...; Put p1 = new Put(row1); Put p2 = new Put(row2); ... Mutate m1 = ProtobufUtil.toMutate(MutateType.PUT, p1); Mutate m2 = ProtobufUtil.toMutate(MutateType.PUT, p2); MutateRowsRequest.Builder mrmBuilder = MutateRowsRequest.newBuilder(); mrmBuilder.addMutationRequest(m1); mrmBuilder.addMutationRequest(m2); CoprocessorRpcChannel channel = t.coprocessorService(ROW); MultiRowMutationService.BlockingInterface service = MultiRowMutationService.newBlockingStub(channel); MutateRowsRequest mrm = mrmBuilder.build(); service.mutateRows(null, mrm);

mutateRows

public void mutateRows(com.google.protobuf.RpcController controller,
                       org.apache.hadoop.hbase.protobuf.generated.MultiRowMutationProtos.MutateRowsRequest request,
                       com.google.protobuf.RpcCallback<org.apache.hadoop.hbase.protobuf.generated.MultiRowMutationProtos.MutateRowsResponse> done)

指定者:

mutateRows 在类中 org.apache.hadoop.hbase.protobuf.generated.MultiRowMutationProtos.MultiRowMutationService

getServices

public Iterable<com.google.protobuf.Service> getServices()

指定者:

getServices 在接口中 Coprocessor

start

public void start(CoprocessorEnvironment env)
           throws IOException

Stores a reference to the coprocessor environment provided by the RegionCoprocessorHost from the region where this coprocessor is loaded. Since this is a coprocessor endpoint, it always expects to be loaded on a table region, so always expects this to be an instance of RegionCoprocessorEnvironment.

指定者:

start 在接口中 Coprocessor

参数:

env - the environment provided by the coprocessor host

抛出:

IOException - if the provided environment is not an instance of RegionCoprocessorEnvironment

stop

public void stop(CoprocessorEnvironment env)
          throws IOException

指定者:

stop 在接口中 Coprocessor

抛出:

IOException
