MongoDB Source Connector

[lepagea01]

I don't consider this a bug, so I'm writing this info here.

The documentation is clear about this. The MongoDB Source Connector supports Atlas DB cluster in dedicated tier M10 and above. Explanations remain vague. And, when one is able to 1) connect and 2) perform initial syncs successfully with lower tiers, support seems subjective. However, there are real problems with MongoDB Atlas' lower tiers, and I believe the official documentation would benefit from some additional info, such as:

⚠️ Note: On MongoDB Atlas shared clusters (M0–M5), change streams may emit internally prefixed database names like abc123_mydb. Tools like Debezium, which Airbyte relies on in CDC scenarios, will ignore change events if configured with the logical name (mydb). This breaks CDC syncs silently. Only M10+ clusters emit namespaces that match user-defined database names.

My two cents.
