Redis Core

Foundational guidance for modeling data in Redis. Covers data-type selection and key-name conventions — the two decisions that most directly drive memory, performance, and maintainability.

When to apply

• Caching objects, sessions, or per-user state.
• Counters, leaderboards, recent-items lists, unique-membership sets.
• Reviewing or refactoring Redis key names.
• Deciding between a Redis Hash and a JSON document for an entity.

1. Choose the right data structure

Pick the type that matches the access pattern, not just the shape of the data.
