The INNODB_LOCK_WAITS
table contains one or more rows for each blocked InnoDB
transaction, indicating the lock it has requested and any locks that are blocking that request.
This table is deprecated and is removed as of MySQL 8.0.1. Use the Performance Schema data_lock_waits
table instead. See Section 27.12.13.2, “The data_lock_waits Table”.
The tables differ in the privileges required: The INNODB_LOCK_WAITS
table requires the global PROCESS
privilege. The data_lock_waits
table requires the usual Performance Schema privilege of SELECT
on the table to be selected from.
The following table shows the mapping from INNODB_LOCK_WAITS
