How do I choose the right consistency model for my application?

Choosing a consistency model depends on your application's requirements for data accuracy and availability. What type of application are you building?

I'm building a real-time collaborative editing tool.

For a real-time collaborative tool, you might want to consider eventual consistency or strong consistency, depending on how critical data accuracy is during edits.

What are the trade-offs between strong and eventual consistency?

Strong consistency ensures that all users see the same data at the same time, but it can lead to higher latency. Eventual consistency allows for faster responses but may result in temporary discrepancies in data.

Can you give me examples of systems that use these models?

Sure! Google Docs uses eventual consistency to allow multiple users to edit simultaneously, while banking systems often use strong consistency to ensure accurate transactions.
