Deadlock detection can be disabled to improve performance and lock wait timeout relied on instead

https://dev.mysql.com/doc/refman/5.7/en/innodb-deadlock-detection.html

On high concurrency systems, deadlock detection can cause a slowdown when numerous threads wait for the same lock. At times, it may be more efficient to disable deadlock detection and rely on the innodb_lock_wait_timeout setting for transaction rollback when a deadlock occurs. Deadlock detection can be disabled using the innodb_deadlock_detect configuration option.
