What is eventual consistency and how is it applied in distributed systems?

Eventual consistency is a consistency model used in distributed systems where updates to a data item will propagate to all replicas eventually, ensuring that all copies of the data will converge to the same value over time.

Can you give me an example of a system that uses eventual consistency?

Sure! A common example is Amazon's DynamoDB, which allows for high availability and partition tolerance by using eventual consistency.

What are the advantages of using eventual consistency?

The main advantages include improved availability, better performance under high load, and the ability to handle network partitions effectively.

Are there any drawbacks to eventual consistency?

Yes, the main drawbacks are potential data conflicts and the challenge of ensuring that all replicas eventually converge, which can complicate application logic.
