Main features

Storing JSON Data

One of the key features of a document database is its ability to natively store JSON data. Being able to store data the same way that it is modeled in the application in the database reduces friction and help improve productivity.

Querying

Amazon DocumentDB enables you to write ad hoc queries to answer questions that you have of your JSON documents. The API enables single document lookups, index scan, regular expression queries, and aggregations.

Flexible Indexing

With Amazon DocumentDB you are able to create single field, compound, and multi-key indexes on your collection that enable you optimize the performance of your query patterns. Reads from the indexes on the primary instance are read-after-write consistent and you can delete or create new indexes at any time.

Separation of storage and compute

Amazon DocumentDB was built from the ground up with a cloud-native database architecture. Its unique architecture separates storage and compute so that each layer can scale independently. Amazon DocumentDB uses a purpose-built, distributed, fault-tolerant, self-healing storage system that is highly available and durable by replicating data six ways across three AWS Availability Zones.
