What is transaction isolation in distributed systems?

What is transaction isolation in distributed systems?

Transaction isolation is a property that ensures transactions are executed independently without interference, crucial in distributed systems.

Why is transaction isolation important?

It's important because it prevents data inconsistencies and ensures that concurrent transactions do not affect each other's outcomes.

What are the different levels of transaction isolation?

The main levels are Read Uncommitted, Read Committed, Repeatable Read, and Serializable, each offering different guarantees.

Can you explain Serializable isolation level?

Serializable is the highest isolation level, ensuring transactions are executed in a way that the results are as if they were executed sequentially.

What are the trade-offs of using higher isolation levels?

Higher isolation levels can lead to increased latency and reduced throughput due to locking and blocking, impacting performance.
