16 Optimizing data processing with Atlas Data Federation
This chapter covers
- Explaining the MongoDB unified Query API
- Understanding the Atlas Federated Database architecture
- Deploying a federated database instance
Atlas Data Federation serves as a distributed query engine that seamlessly integrates various data sources within and beyond Atlas, such as external cloud storage. The federation setup allows the creation of virtual databases and collections, which serve as pathways to access the stored data. It enables you to perform complex analytical queries across combined data sets from historical and live data sources, ensuring efficient data management and deep analytical insights. This setup is particularly useful when you need to maintain a consistent, comprehensive view of your data for strategic decision-making.
