Description: The ‘InnoDB_lock_wait_timeout’ parameter is a crucial configuration in the MySQL database management system, specifically in its InnoDB storage engine. This parameter defines the maximum time a transaction will wait to acquire a lock before an error occurs. In database environments where multiple transactions may attempt to access the same resources simultaneously, locks are essential for maintaining data integrity. However, if a transaction cannot obtain the necessary lock within the time specified by ‘InnoDB_lock_wait_timeout’, it will be aborted, and an error will be generated, allowing developers and database administrators to handle the situation appropriately. This parameter is particularly relevant in high-concurrency applications, where performance and availability are critical. Adjusting this value can help optimize database behavior, avoiding prolonged waits that could affect user experience and system efficiency. By default, the value of ‘InnoDB_lock_wait_timeout’ is set to 50 seconds, but it can be modified according to the specific needs of the database environment.
