max_delayed_threads
Information
Do not start more than this number of threads to handle INSERT DELAYED statements. If you try to insert data into a new table after all INSERT DELAYED threads are in use the row is inserted as if the DELAYED attribute wasn't specified. If you set this to 0 MySQL never creates a thread to handle DELAYED rows; in effect doing so disables DELAYED entirely. This variable was added in MySQL 3.23.0.
