What does Redis do?

Redis is an in-memory data structure store used as a database, cache, and message broker. In Chevereto, Redis handles caching of application data and session storage, significantly improving performance by reducing database queries.

Chevereto uses Redis cache for:

• Settings
• Categories
• Listings (guests)
• Pages
• Top Tags
• Variables
• Sessions

Application cache

See the Cache variables section for environment variables to configure Redis application-level cache in Chevereto.

Session storage

See the Session variables section for environment variables to configure Redis session storage in Chevereto.

Fine-tuning

Redis stores frequently accessed data for quick retrieval, reducing database load. You can set cache expiration to keep data fresh and minimize stale cache.

Use CHEVERETO_MAX_CACHE_TTL to set the maximum time to live (TTL) for cached items. Set to 0 to disable TTL (perpetual cache).
