What are the best practices for handling database concurrency?

Handling database concurrency effectively is crucial for maintaining data integrity. Some best practices include using optimistic concurrency control, implementing locking mechanisms, and ensuring proper transaction isolation levels.

Can you explain optimistic concurrency control?

Optimistic concurrency control allows multiple transactions to proceed without locking resources. It checks for conflicts before committing changes, which can improve performance in low-contention scenarios.

What are the different types of locking mechanisms?

There are several types of locking mechanisms, including row-level locks, table-level locks, and shared vs. exclusive locks. Each has its use cases depending on the level of concurrency required.

How do I choose the right transaction isolation level?

Choosing the right transaction isolation level depends on your application's needs for consistency versus performance. Common levels include Read Uncommitted, Read Committed, Repeatable Read, and Serializable.

What are some common pitfalls to avoid in database concurrency?

Common pitfalls include deadlocks, excessive locking, and not properly handling transaction rollbacks. It's important to monitor and optimize your concurrency strategy.
