Amazon DocumentDB Compatibility

Version Information

Amazon DocumentDB claims support for MongoDB v4.0 and MongoDB v5.0. These versions do not support all the newer features and functionality in the versions of MongoDB available on MongoDB Atlas. DocumentDB's compatibility with even these older versions is incomplete, and applications might not work as expected.

Tip
