Method Detail

getSharedClientEventloopGroup

public static io.netty.channel.EventLoopGroup getSharedClientEventloopGroup()

make this factory static thus all clients can share its thread pool. NioClientSocketChannelFactory has only one method newChannel() visible for user, which is thread-safe

getSharedClientEventloopGroup

public static io.netty.channel.EventLoopGroup getSharedClientEventloopGroup(int workerNum)

make this factory static thus all clients can share its thread pool. NioClientSocketChannelFactory has only one method newChannel() visible for user, which is thread-safe

Parameters:

workerNum - The number of workers

getSharedClientEventloopGroup

public static io.netty.channel.EventLoopGroup getSharedClientEventloopGroup(RpcChannelFactory.ClientChannelId clientId,
                                                            int workerNum)

This function return eventloopgroup by key. Fetcher client will have one or more eventloopgroup for its throughput.

Parameters:

clientId -

workerNum -

Returns:

isEventLoopGroupShuttingDown

protected static boolean isEventLoopGroupShuttingDown(io.netty.channel.EventLoopGroup eventLoopGroup)

createClientEventloopGroups

protected static Queue<io.netty.channel.EventLoopGroup> createClientEventloopGroups(RpcChannelFactory.ClientChannelId clientId,
                                                                 int workerNum)

createClientEventloopGroup

protected static io.netty.channel.EventLoopGroup createClientEventloopGroup(String name,
                                                         int workerNum)

createServerChannelFactory

public static io.netty.bootstrap.ServerBootstrap createServerChannelFactory(String name,
                                                            int workerNum)

shutdownGracefully

public static void shutdownGracefully()
