View on GitHubWhat This Skill Does
Configures MongoDB client connections across supported driver languages. Tunes pool sizes, timeouts, and reuse patterns based on deployment type, workload, and concurrency. Diagnoses connection errors like pool exhaustion, ECONNREFUSED, and socket timeouts.
Grounds pool and timeout values in the actual deployment topology, driver type, and workload instead of copying arbitrary numbers from a blog post.
When to use it
- Sizing maxPoolSize for a Lambda function hitting an Atlas cluster
- Debugging MongoWaitQueueTimeoutError in a Node.js API under load
- Setting socketTimeoutMS for long-running analytical aggregations
- Reusing a MongoClient across warm serverless invocations
- Calculating total server connections for a 10-instance replica set deployment
