MongoDB vs. DocumentDB: Which Is Right for You?

Deciding between MongoDB and Amazon DocumentDB can be challenging due to recent licensing changes and compatibility issues. MongoDB, Inc. has altered its license to prevent future imitations, while Amazon developed DocumentDB, a scalable, fully-managed service compatible with MongoDB 3.6 API but with notable limitations. DocumentDB is tailored for high throughput and large-scale data management, featuring automatic scaling and fault tolerance, but lacks support for newer MongoDB features like multi-statement ACID transactions and certain data types. Despite these gaps, DocumentDB may appeal to those requiring extensive scalability and integration within AWS's ecosystem, but potential vendor lock-in and missing MongoDB advancements should be considered.
