What are the performance trade-offs of isolation levels?

Can you explain the different isolation levels in databases?

Sure! The main isolation levels are Read Uncommitted, Read Committed, Repeatable Read, and Serializable. Each level balances consistency and performance differently.

What are the performance trade-offs of using Serializable isolation?

Using Serializable isolation provides the highest level of consistency but can lead to increased locking and reduced concurrency, impacting performance.

How does Read Committed compare to Repeatable Read in terms of performance?

Read Committed allows for more concurrency since it doesn't hold locks for the duration of a transaction, while Repeatable Read can lead to more locks and potential performance bottlenecks.

Are there scenarios where I should avoid using Serializable?

Yes, if your application requires high throughput and can tolerate some anomalies, using Serializable may not be ideal due to its performance overhead.
