It is read-only and can be set by using the PERSIST_ONLY  keyword or the  @@persist_only  qualifier with the  SET  statement. The  --skip- Tells the replica server not to start the replication I/O and SQL threads when the server starts. To start the threads later, use a  START REPLICA | SLAVE  statement. This variable affects only the client that issues a  STOP REPLICA | SLAVE  statement. When the timeout is reached, the issuing client returns an error message stating that the command execution is incomplete. The client then stops waiting for the replication I/O and SQL threads to stop, but the replication threads continue to try to stop, and the  STOP REPLICA | SLAVE  instruction remains in effect. Once the replication threads are no longer busy, the  STOP REPLICA | SLAVE  statement is executed and the replica stops. The maximum and default value of  rpl_stop_slave_timeout  is 31536000 seconds (1 year). The minimum is 2 seconds. Changes to this variable take effect for subsequent  STOP REPLICA | SLAVE statements. You can control the length of time (in seconds) that  STOP REPLICA | SLAVE  waits before timing out by setting this variable. This can be used to avoid deadlocks between  STOP REPLICA | SLAVE  and other SQL statements using different client connections to the replica. • skip_slave_start • rpl_stop_slave_timeout The semisynchronous replication debug trace level on the replica server. See rpl_semi_sync_master_trace_level  for the permissible values. This variable is available only if the replica-side semisynchronous replication plugin is installed.
