numIoThreads

@Config(value="num.io.threads")
 @Default(value="8")
public final int numIoThreads

The number of io threads that the server uses for carrying out network requests

queuedMaxRequests

@Config(value="queued.max.requests")
 @Default(value="500")
public final int queuedMaxRequests

The number of queued requests allowed before blocking the network threads

port

@Config(value="port")
 @Default(value="6667")
public final int port

The port to listen and accept connections on

hostName

@Config(value="host.name")
 @Default(value="localhost")
public final java.lang.String hostName

Hostname of server. If this is set, it will only bind to this address. If this is not set, it will bind to all interfaces, and publish one to ZK

public final int socketReceiveBufferBytes

The SO_RCVBUFF buffer of the socket sever sockets

socketRequestMaxBytes

@Config(value="socket.request.max.bytes")
 @Default(value="104857600")
public final int socketRequestMaxBytes

The maximum number of bytes in a socket request

networkClientEnableConnectionReplenishment

@Config(value="network.client.enable.connection.replenishment")
 @Default(value="false")
public final boolean networkClientEnableConnectionReplenishment

Whether the client should attempt to replenish connections when the number of connections to a host drops below a minimum number of active connections.

networkClientMaxReplenishmentPerHostPerSecond

@Config(value="network.client.max.replenishment.per.host.per.second")
 @Default(value="1")
public final int networkClientMaxReplenishmentPerHostPerSecond

The max number of new connections to a remote host that should be created per second when replenishing connections.

selectorExecutorPoolSize

@Config(value="selector.executor.pool.size")
 @Default(value="4")
public final int selectorExecutorPoolSize

The size of the pool if selector executor pool is employed. When size is 0, executor pool won't be used.

selectorMaxKeyToProcess

@Config(value="selector.max.key.to.process")
 @Default(value="-1")
public final int selectorMaxKeyToProcess

The max number of ready keys can be processed in a selector.poll() call. No limitation if -1 is used.

selectorUseDirectBuffers

@Config(value="selector.use.direct.buffers")
 @Default(value="false")
public final boolean selectorUseDirectBuffers
