Why MySQL 8.0 Upgrade Can Suddenly Slow Down Queries: The Hidden Lock Table Trap

After upgrading from MySQL 5.7 to 8.0, a client experienced a flood of slow queries despite low system load; the root cause was a change in the sys.innodb_lock_waits view that now relies on performance_schema.data_locks, whose large lock table holds a global mutex and blocks other transactions, a problem solved by adding an index to reduce lock volume.
