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, performance, and versatility, supporting various data models with features like auto-scaling and geo-replication. The platform excels in real-time analytics and integrates seamlessly with Microsoft products. However, complex query language, costly pricing, MongoDB API integration issues, and insufficient backup functionality affect usability, particularly in data restoration and integration with Databricks. SQL support and documentation need enhancement for improved performance across different applications.
