What are some real-world examples of causal consistency?

Causal consistency is often seen in distributed systems. For example, in collaborative applications like Google Docs, changes made by one user are visible to others in a way that respects the order of operations.

Can you explain how it works in Google Docs?

Sure! In Google Docs, when one user edits a document, that change is propagated to other users in a way that ensures they see the updates in the order they were made, maintaining a consistent view.

Are there other applications that use causal consistency?

Yes, social media platforms like Facebook also use causal consistency to ensure that comments and likes appear in the correct order, reflecting the sequence of user interactions.

What are the benefits of using causal consistency?

The main benefits include improved user experience, as users see updates in a logical order, and reduced confusion, as it prevents scenarios where users see conflicting information.
