The global system variable slave_transaction_retries affects replication as follows: If the replication SQL thread fails to execute a transaction because of an InnoDB deadlock or because it exceeded the InnoDB innodb_lock_wait_timeout value, or the NDB TransactionDeadlockDetectionTimeout or TransactionInactiveTimeout value, the replica automatically retries the transaction slave_transaction_retries times before stopping with an error. The default value is 10. The total retry count can be seen in the output of SHOW STATUS; see Section 5.1.9, “Server Status Variables”.
