This feature controls the TCP keep-alive feature timings per socket. Applications deployed by users had prerequisites concerning the system call latencies. Using gluster as the file-system adds further network latency to the existing system-call latency. These gluster options opened to the user will help them fine-tune the application to an acceptable network latency beyond which the TCP socket will be assumed as disconnected. Default values assigned to these options configure every TCP socket to the system default values when no such options are explicitly set. The gluster volume options opened to the users are: * server.tcp-user-timeout * client.tcp-user-timeout * transport.socket.keepalive-time * transport.socket.keepalive-interval * transport.socket.keepalive-count These options are 1:1 compatible with similar options described in the TCP(7) manual page. This feature provides a mechanism to fine tune the application behaviour for better user experience.
