  • @PublicEvolving
@Deprecated
public class QueryableStateOptions

    The set of configuration options relating to Queryable State.

    • Field Detail

      • PROXY_PORT_RANGE

        public static final ConfigOption<String> PROXY_PORT_RANGE
        Deprecated.
        The config parameter defining the server port range of the queryable state proxy.

        A proxy runs on each Task Manager, so many proxies may run on the same machine.

        Given this, and to avoid port clashes, the user can specify a port range and the proxy will bind to the first free port in that range.

        The specified range can be:

        1. a port: "9123",
        2. a range of ports: "50100-50200", or
        3. a list of ranges and ports: "50100-50200,50300-50400,51234"

        The default port is 9069.

      • PROXY_NETWORK_THREADS

        public static final ConfigOption<Integer> PROXY_NETWORK_THREADS
        Deprecated.
        Number of network (event loop) threads for the client proxy (0 => #slots).

      • PROXY_ASYNC_QUERY_THREADS

        public static final ConfigOption<Integer> PROXY_ASYNC_QUERY_THREADS
        Deprecated.
        Number of async query threads for the client proxy (0 => #slots).

      • SERVER_PORT_RANGE

        public static final ConfigOption<String> SERVER_PORT_RANGE
        Deprecated.
        The config parameter defining the server port range of the queryable state server.

        A state server runs on each Task Manager, so many server may run on the same machine.

        Given this, and to avoid port clashes, the user can specify a port range and the server will bind to the first free port in that range.

        The specified range can be:

        1. a port: "9123",
        2. a range of ports: "50100-50200", or
        3. a list of ranges and ports: "50100-50200,50300-50400,51234"

        The default port is 9067.

      • SERVER_NETWORK_THREADS

        public static final ConfigOption<Integer> SERVER_NETWORK_THREADS
        Deprecated.
        Number of network (event loop) threads for the KvState server (0 => #slots).

      • SERVER_ASYNC_QUERY_THREADS

        public static final ConfigOption<Integer> SERVER_ASYNC_QUERY_THREADS
        Deprecated.
        Number of async query threads for the KvStateServerHandler (0 => #slots).

      • ENABLE_QUERYABLE_STATE_PROXY_SERVER

        public static final ConfigOption<Boolean> ENABLE_QUERYABLE_STATE_PROXY_SERVER
        Deprecated.
        Option whether the queryable state proxy and server should be enabled where possible and configurable.

        Queryable state proxy and server are still more experimental features, hence disabled unless they are enable in user configuration.

      • CLIENT_NETWORK_THREADS

        public static final ConfigOption<Integer> CLIENT_NETWORK_THREADS
        Deprecated.
        Number of network (event loop) threads for the KvState client (0 => Use number of available cores).
