How do we resolve persistent MongoDB Atlas connection timeout issues when our application pods scale up rapidly under heavy traffic loads in our cloud environment?
Fan-out diagram
Seed → topic clusters → sub-queries, per model.
Badge and edge weight = share of passes that produced the query. Hover a query for its intent and routing format.
Query classes
Google's semantic query class for every sub-query: what kind of answer each search is after, simulated vs real.
Classes come from the query-classifier (a local Laya model). 2 of 2 calls are low-confidence (under 50%) — hover a query in the table to see its confidence. 35 queries are still being classified.
What the models actually searched
Each model answered the query with its own web search. These are the searches it ran, matched to the closest simulated query.

- Atlas Service Limits - Atlas · mongodb.com
- Troubleshoot Connection Issues - Atlas · mongodb.com

Semantic map
Every query placed by meaning (EmbeddingGemma 2, 256-d). Shaded regions are topics, nearby points are near-paraphrases, and a circle's size is how often the query came back.
