      • getMaxConnectionThreadPoolSize

        public int getMaxConnectionThreadPoolSize()

      • setMaxConnectionThreadPoolSize

        public void setMaxConnectionThreadPoolSize​(int maxConnectionThreadPoolSize)
        Set the number of threads to be used for processing connections. Defaults to Integer.MAX_SIZE. Set this value to be lower to reduce the number of simultaneous connection attempts. If not set then the maximum number of threads will generally be controlled by the transport maxConnections setting: TcpTransportServer.setMaximumConnections(int).

        Note that this setter controls two thread pools because connection attempts require 1 thread to start processing the connection and another thread to read from the socket and to detect the protocol. Two threads are needed because some transports block on socket read so the first thread needs to be able to abort the second thread on timeout. Therefore this setting will set each thread pool to the size passed in essentially giving 2 times as many potential threads as the value set.

        Both thread pools will close idle threads after a period of time essentially allowing the thread pools to grow and shrink dynamically based on load.

        Parameters:
        maxConnectionThreadPoolSize -
