What are the implications of using serializable isolation level?

What does the serializable isolation level mean in databases?

The serializable isolation level is the highest level of isolation in database transactions, ensuring complete isolation from other transactions.

What are the implications of using this isolation level?

Using serializable isolation can prevent phenomena like dirty reads and non-repeatable reads, but it may lead to increased contention and reduced performance.

Are there any scenarios where I should avoid using it?

Yes, if your application requires high throughput and can tolerate some anomalies, lower isolation levels like read committed might be more suitable.

How does it compare to other isolation levels?

Serializable is stricter than repeatable read, which allows some concurrency. It ensures complete isolation but can lead to more locking and blocking.
