方法详细资料

getProxyPortRange

public Iterator<Integer> getProxyPortRange()

Returns the port range where the queryable state client proxy can listen. See QueryableStateOptions.PROXY_PORT_RANGE.

getStateServerPortRange

public Iterator<Integer> getStateServerPortRange()

Returns the port range where the queryable state server can listen. See QueryableStateOptions.SERVER_PORT_RANGE.

numProxyServerThreads

public int numProxyServerThreads()

Returns the number of threads for the query proxy NIO event loop. These threads only process network events and dispatch query requests to the query threads.

numProxyQueryThreads

public int numProxyQueryThreads()

Returns the number of query threads for the queryable state client proxy.

numStateServerThreads

public int numStateServerThreads()

Returns the number of threads for the query server NIO event loop. These threads only process network events and dispatch query requests to the query threads.

numStateQueryThreads

public int numStateQueryThreads()

Returns the number of threads for the thread pool that performs the actual state lookup. These threads perform the actual state lookup.

toString

disabled

public static QueryableStateConfiguration disabled()

Gets the configuration describing the queryable state as deactivated.

fromConfiguration

public static QueryableStateConfiguration fromConfiguration(org.apache.flink.configuration.Configuration config)

Creates the QueryableStateConfiguration from the given Configuration.
