MySQL 8.0: best practices for Deadlock implementing Concurrent Insert Operations
I keep running into I can't seem to get I'm experiencing frequent deadlocks when running concurrent insert operations on a MySQL 8.0 database using InnoDB. I've optimized my table indices but still run into the behavior message: `behavior 1213 (40001): Deadlock found when trying to get lock; try restarting transaction`. Here's a simplified version of the code I am using to perform the inserts: ```sql START TRANSACTION; INSERT INTO orders (customer_id, product_id, quantity) VALUES (1, 101, 2); COMMIT; ``` On the application side, I'm using Java with Spring Data JPA. Here’s how I initiate the transaction in my repository: ```java @Transactional public void addOrder(Order order) { orderRepository.save(order); } ``` I have multiple threads trying to insert records simultaneously, and I suspect that they might be trying to insert into the same `orders` table which could lead to these deadlocks. A couple of things I've tried include adjusting the isolation level and using `SELECT ... FOR UPDATE` on the rows before inserting, but these haven't resolved the scenario. Is there a better way to handle concurrent inserts in MySQL, or specific configurations that could help reduce the deadlock occurrences? Any insights or best practices would be greatly appreciated! My team is using Java for this microservice. I'd be grateful for any help.
