dba-mongodb

What problem does it solve?

MongoDB provides powerful capabilities but teams often struggle to identify performance bottlenecks, indexing gaps, and modeling decisions that impact scalability and reliability. This skill catalogs heuristics across indexing, data modeling, queries, migrations, TTL retention, shard keys, security, and concurrency, surfacing actionable recommendations with Mongo shell commands where applicable.

Core Features & Use Cases

• Indexing heuristics: detect missing indexes, ESL/ESR ordering issues, and index strategy against hot predicates.
• Modeling recommendations: advise embed vs reference decisions to balance read patterns and document growth.
• Query & migration guidance: highlight anti-patterns in queries, suggest safer migration strategies, and outline validation checks.
• Retention & capacity insights: identify TTL usage needs and shard-key health to improve scale and resilience.
• Security & governance: flag potential exposure risks and provide remediation steps with concrete commands. All findings include a Mongo shell command that can be run to reproduce or fix the issue.

Quick Start

Run the dba-mongodb skill against your MongoDB projects to surface a prioritized findings report and remediation plan.
