SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill resolves inconsistencies in how MongoDB is utilized within the stack, preventing common pitfalls like improper schema versioning, incorrect ID strategies, and inefficient query patterns.

Core Features & Use Cases

  • Data Placement Strategy: Provides clear rules for when to choose MongoDB over Postgres based on schema flexibility and write patterns.
  • Operational Conventions: Enforces best practices for document versioning, UUID usage, and index management via migrations.
  • Use Case: When designing a new microservice, use this skill to determine if your data model belongs in a document store and to ensure your repository queries are optimized and index-backed.

Quick Start

Use the mongodb skill to validate my proposed collection schema and index strategy for the new user activity logs.

FAQPage Schema
When should I choose MongoDB over Postgres for microservice data persistence?

MongoDB schema versioning works by enforcing strict document version tracking alongside UUID-based identification. This strategy prevents data inconsistencies and ensures safe, traceable database migrations across your microservices architecture.

How do I optimize MongoDB repository queries for index-driven performance?

Optimize MongoDB repository queries by designing an index-driven strategy that backs all expected data access patterns. Validate your proposed collection schema and indexes early to ensure efficient query performance within your microservices.

How do you handle database migrations and index management in a MongoDB architecture?

Handle MongoDB database migrations and index management by enforcing operational conventions through structured migration scripts. This process maintains index-driven query performance and applies necessary schema updates without disrupting document persistence.

What are common pitfalls when designing document schemas for MongoDB?

Common MongoDB document schema pitfalls include improper schema versioning, incorrect UUID strategies, and inefficient query patterns. Standardizing your data modeling prevents these architectural inconsistencies and ensures reliable document-oriented storage.

Does my data model belong in a document store or a relational database?

Your data model belongs in a document store if it requires high schema flexibility and specific write patterns unsuited for relational rules. Evaluate your data placement strategy against these architectural needs to determine the correct persistence layer.
