The MongoDB connector is supported both as a source and a destination. It is built into dsync/dsynct and connects directly using a MongoDB connection string.
Configuration
Provide a standard MongoDB connection string as the source or destination argument:
mongodb://username:password@host:port
This works with MongoDB Atlas (dedicated and serverless), self-managed installations, AWS DocumentDB, and Azure DocumentDB (Cosmos DB vCore).
Data Type
The MongoDB connector uses BSON.
ID Format
The ID is a single field called _id. By default, MongoDB uses ObjectID values for _id, but any BSON type is supported.
