How do I choose the right transaction isolation level?

What factors should I consider when choosing a transaction isolation level?

You should consider factors like data consistency requirements, performance, and the specific use case of your application.

Can you explain the different isolation levels available?

Sure! The main isolation levels are Read Uncommitted, Read Committed, Repeatable Read, and Serializable. Each has its trade-offs.

What is the default isolation level in most databases?

Most databases use Read Committed as the default isolation level, but it can vary depending on the database system.

How does the isolation level affect performance?

Higher isolation levels can lead to more locking and blocking, which may reduce performance, while lower levels can increase concurrency.
