Change feed is a pretty amazing feature. Once you make the changes, they are quickly read for you, and then you also have geo-replication. You can do a lot of things in your region, and the same regions can be replicated all over the world.
Microsoft Azure Cosmos DB excels in scalability, seamlessly integrating with platforms for efficient data management and analytics, offering multi-region support and real-time capabilities.

Documentation and support require enhancement, particularly for handling larger documents due to the 2 MB size constraint, presenting challenges for tech buyers.
