Constructor Detail

KvStateClientProxyImpl

public KvStateClientProxyImpl(String bindAddress,
                              Iterator<Integer> bindPortIterator,
                              Integer numEventLoopThreads,
                              Integer numQueryThreads,
                              org.apache.flink.queryablestate.network.stats.KvStateRequestStats stats)

Creates the Queryable State Client Proxy.

The server is instantiated using reflection by the QueryableStateUtils.createKvStateClientProxy(InetAddress, Iterator, int, int, KvStateRequestStats).

The server needs to be started via start() in order to bind to the configured bind address.

Parameters:

bindAddress - the address to listen to.

bindPortIterator - the port range to try to bind to.

numEventLoopThreads - number of event loop threads.

numQueryThreads - number of query threads.

stats - the statistics collector.
