MySQL InnoDB lock wait timeout
Lock wait timeout exceeded.*try restarting transaction
Fixes
- 1.Retry the transaction — another transaction is holding a conflicting lock
- 2.Check blocking transactions: SELECT * FROM information_schema.INNODB_TRX
- 3.Increase innodb_lock_wait_timeout if workload legitimately needs longer waits, or optimize the blocking query
