DocumentDB
Overview
AWS DocumentDB is a fully managed document database service that offers some MongoDB API compatibility. It supports MongoDB versions 3.6, 4.0, and 5.0 APIs. While Amazon DocumentDB aims to be compatible with MongoDB, it does not support every MongoDB 5.0 feature. It provides a semi-MongoDB-compatible environment that can be used with existing MongoDB applications and tools, though it may not fully support all MongoDB features.
See this page for more information on compatibility
