Amazon DocumentDB is compatible with MongoDB 3.6, 4.0, and 5.0 drivers and tools. A vast majority of the applications, drivers, and tools that customers already use today with their open-source MongoDB non-relational database can be used with Amazon DocumentDB. Amazon DocumentDB emulates the responses that a client expects from a MongoDB server by implementing the Apache 2.0 open source MongoDB 3.6, 4.0, and 5.0 APIs on a purpose-built, distributed, fault-tolerant, and self-healing storage system that gives customers the performance, scalability, and availability they need when operating mission-critical MongoDB workloads at scale.
