createKvStateClientProxy

public static KvStateClientProxy createKvStateClientProxy(InetAddress address,
                                                          Iterator<Integer> ports,
                                                          int eventLoopThreads,
                                                          int queryThreads,
                                                          org.apache.flink.queryablestate.network.stats.KvStateRequestStats stats)

Initializes the client proxy responsible for receiving requests from the external (to the cluster) client and forwarding them internally.

参数:

address - the address to bind to.

ports - the range of ports the proxy will attempt to listen to (see QueryableStateOptions.PROXY_PORT_RANGE).

eventLoopThreads - the number of threads to be used to process incoming requests.

queryThreads - the number of threads to be used to send the actual state.

stats - statistics to be gathered about the incoming requests.

返回:

the client proxy.

createKvStateServer

public static KvStateServer createKvStateServer(InetAddress address,
                                                Iterator<Integer> ports,
                                                int eventLoopThreads,
                                                int queryThreads,
                                                KvStateRegistry kvStateRegistry,
                                                org.apache.flink.queryablestate.network.stats.KvStateRequestStats stats)

Initializes the server responsible for sending the requested internal state to the client proxy.

参数:

address - the address to bind to.

ports - the range of ports the state server will attempt to listen to (see QueryableStateOptions.SERVER_PORT_RANGE).

eventLoopThreads - the number of threads to be used to process incoming requests.

queryThreads - the number of threads to be used to send the actual state.

kvStateRegistry - the registry with the queryable state.

stats - statistics to be gathered about the incoming requests.

返回:

the state server.
