Question 1

A global social media company uses Azure Cosmos DB to store user posts. The database is replicated across 5 regions globally.

The application requires that when a user makes a post, their followers in other regions see the posts in the exact order they were written. However, to maintain high performance, the company is willing to accept a slight delay (up to 5 seconds) before the posts appear in other regions.

Which Cosmos DB consistency level should you configure?

Accepted Answer

Match 'exact order' and 'slight delay (up to 5 seconds)' to the consistency level that allows configuring a time/version lag while maintaining order.
