public class KvStateClientProxyHandler
extends org.apache.flink.queryablestate.network.AbstractServerHandler<org.apache.flink.queryablestate.messages.KvStateRequest,org.apache.flink.queryablestate.messages.KvStateResponse>

This handler acts as an internal (to the Flink cluster) client that receives the requests from external clients, executes them by contacting the Job Manager (if necessary) and the Task Manager holding the requested state, and forwards the answer back to the client.

                                 int queryExecutorThreads,
                                 org.apache.flink.queryablestate.network.messages.MessageSerializer<org.apache.flink.queryablestate.messages.KvStateRequest,org.apache.flink.queryablestate.messages.KvStateResponse> serializer,
                                 org.apache.flink.queryablestate.network.stats.KvStateRequestStats stats)

Create the handler used by the KvStateClientProxyImpl.

参数:

proxy - the proxy using the handler.

queryExecutorThreads - the number of threads used to process incoming requests.

serializer - the MessageSerializer used to (de-) serialize the different messages.

stats - server statistics collector.
