Saves the current Performance Schema configuration. This enables you to alter the configuration temporarily for debugging or other purposes, then restore it to the previous state by invoking the ps_setup_reload_saved() procedure.

To prevent other simultaneous calls to save the configuration, ps_setup_save() acquires an advisory lock named sys.ps_setup_save by calling the GET_LOCK() function. ps_setup_save() takes a timeout parameter to indicate how many seconds to wait if the lock already exists (which indicates that some other session has a saved configuration outstanding). If the timeout expires without obtaining the lock, ps_setup_save() fails.

It is intended you call ps_setup_reload_saved() later within the same session as ps_setup_save() because the configuration is saved in TEMPORARY tables. ps_setup_save() drops the temporary tables and releases the lock. If you end your session without invoking ps_setup_save(), the tables and lock disappear automatically.

This procedure disables binary logging during its execution by manipulating the session value of the sql_log_bin system variable. That is a restricted operation, so the procedure requires privileges sufficient to set restricted session variables. See Section 5.1.9.1, “System Variable Privileges”.
