What are the best practices for using transaction isolation levels?

What are the best practices for using transaction isolation levels in databases?

The best practices include understanding the trade-offs between consistency and performance, using the lowest isolation level that meets your needs, and testing your application under different isolation levels.

Can you explain the different isolation levels?

Sure! The main isolation levels are Read Uncommitted, Read Committed, Repeatable Read, and Serializable. Each level offers a different balance of consistency and performance.

When should I use Serializable isolation level?

Use Serializable when you need complete isolation and consistency, such as in financial transactions where accuracy is critical.

What are the risks of using lower isolation levels?

Lower isolation levels can lead to phenomena like dirty reads, non-repeatable reads, and phantom reads, which may compromise data integrity.
