Amazon DocumentDB is a scalable, highly durable, and fully managed database service for operating mission-critical MongoDB workloads.
Amazon DocumentDB continues to increase compatibility with MongoDB and today added support for the following MongoDB APIs and indexing improvements in DocumentDB 3.6 and 4.0:
- $mergeObjects: Aggregation pipeline operator that combines multiple documents into a single document
- $reduce: Aggregation operator that applies an expression to each element in an array and combines them into a single value
These capabilities are supported in all regions where Amazon DocumentDB is available. All supported MongoDB APIs and aggregation pipeline capabilities for Amazon DocumentDB can be found here.
