MongoDB Atlas is a fully managed cloud database, widely adopted for AI and RAG applications — particularly through Atlas Vector Search in LLM pipelines. It makes sense to explicitly validate pw.io.mongodb against Atlas to improve Pathway usability for the AI-agent use case.

The existing connector interface should be compatible with Atlas. If that's the case, we still need:

• Integration tests that verify Atlas compatibility explicitly and would trigger an alert if something breaks;
• Clear documentation making it evident that Pathway can be used with MongoDB Atlas, including Atlas Vector Search workflows.
