What are the best practices for transaction isolation in databases?

The best practices for transaction isolation include using the appropriate isolation level, minimizing lock contention, and ensuring data consistency.

Can you explain the different isolation levels?

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

What are the trade-offs of using Serializable isolation?

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

How can I minimize lock contention?

You can minimize lock contention by keeping transactions short, using appropriate isolation levels, and optimizing queries to reduce the time locks are held.
