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 offers exceptional scalability, speed, and low latency with features like auto-scaling and global synchronization. It supports multiple data models and real-time analytics, enhancing its flexibility. However, its complex pricing, querying limitations, and inconsistent customer support may pose challenges. While integration with solutions like Databricks and MongoDB and efficient data handling require improvements, Cosmos DB remains a robust option for diverse applications requiring advanced functionalities and geographic distribution.
