NoSQL Patterns Skill

When to Activate

• Evaluating whether to use MongoDB, DynamoDB, or Redis over Postgres
• Designing a MongoDB schema (embedding vs. referencing decisions)
• Designing DynamoDB tables (single-table design, access patterns)
• Building high-throughput key/value or session storage
• Handling unstructured or highly variable document shapes
• Defining all DynamoDB access patterns upfront before committing to a key schema and GSI layout
• Deciding whether to embed or reference child data in MongoDB to avoid unbounded document growth or N+1 lookup patterns
