Class Summary

Class	Description
AbstractRpcClient<T extends RpcConnection>	Provides the basics for a RpcClient implementation like configuration and Logging.
AbstractRpcClient.AbstractRpcChannel

AbstractRpcClient.RpcChannelImplementation	Async rpc channel that goes via hbase rpc.
AdaptiveLifoCoDelCallQueue	Adaptive LIFO blocking queue utilizing CoDel algorithm to prevent queue overloading.
BalancedQueueRpcExecutor	An RpcExecutor that will balance requests evenly across all its queues, but still remains efficient with a single queue via an inlinable queue balancing mechanism.
BlockingRpcCallback<R>	Simple RpcCallback implementation providing a Future-like BlockingRpcCallback.get() method, which will block util the instance's BlockingRpcCallback.run(Object) method has been called.
BlockingRpcClient	Does RPC against a cluster.
BlockingRpcConnection	Thread that reads responses and notifies callers.
BufferCallBeforeInitHandler	We will expose the connection to upper layer before initialized, so we need to buffer the calls passed in and write them out once the connection is established.
BufferCallBeforeInitHandler.BufferCallEvent
BufferChain	Chain of ByteBuffers.
Call	A call waiting for a value.
CallEvent	Used to tell netty handler the call is cancelled, timeout...
CallQueueInfo
CallRunner	The request processing logic, which is usually executed in thread pools provided by an RpcScheduler.
CellBlockBuilder	Helper class for building cell block.
CellBlockBuilder.ByteBufferOutputStreamSupplier
CellBlockBuilder.ByteBufOutputStreamSupplier
ConnectionId	This class holds the address and the user ticket, etc.
CoprocessorRpcUtils	Utilities for handling coprocessor rpc service calls.
CoprocessorRpcUtils.BlockingRpcCallback<R>	Simple RpcCallback implementation providing a Future-like BlockingRpcCallback.get() method, which will block util the instance's BlockingRpcCallback.run(Object) method has been called.
DelegatingHBaseRpcController	Simple delegating controller for use with the RpcControllerFactory to help override standard behavior of a HBaseRpcController.
FailedServers	A class to manage a list of servers that failed recently.
FastPathBalancedQueueRpcExecutor	Balanced queue executor with a fastpath.
FastPathRpcHandler
FastPathRWQueueRpcExecutor	RPC Executor that extends RWQueueRpcExecutor with fast-path feature, used in FastPathBalancedQueueRpcExecutor.
FifoRpcScheduler	A very simple RpcScheduler} that serves incoming requests in order.
FifoRpcScheduler.FifoCallRunner
HBaseRpcControllerImpl	Get instances via RpcControllerFactory on client-side.
HeapByteBufAllocator	A pooled ByteBufAllocator that does not prefer direct buffers regardless of platform settings.

RpcHandler	Thread to handle rpc call.
RpcScheduler	An interface for RPC request scheduling algorithm.
RpcScheduler.Context	Exposes runtime information of a RpcServer that a RpcScheduler may need.
RpcSchedulerContext
RpcServer	An RPC server that hosts protobuf described Services.
RpcServer.BlockingServiceAndInterface	Datastructure for passing a BlockingService and its associated class of protobuf service interface.
