Solid Cache is a database-backed ActiveSupport::Cache::Store for Rails that stores cache entries in SQL databases (SQLite, MySQL, PostgreSQL) instead of memory-only stores like Redis or Memcached. It leverages fast SSDs to enable much larger caches with negligible access-time penalty, and ships as the default cache store in Rails 8.

Use cases

• replace Redis or Memcached with a database-backed Rails cache store
• keep a very large application cache on disk instead of limited RAM
• simplify Rails infrastructure by removing a separate cache server
• configure a production cache store for a new Rails 8 app
• store cache entries in SQLite, MySQL, or PostgreSQL
• set cache size and expiration policies like max_age and max_size

When to choose

• you run Rails and want a durable, large cache without operating Redis or Memcached
• your cache is bigger than fits comfortably in memory and SSD latency is acceptable
• you want fewer moving parts in your production stack

When to avoid

• you need microsecond-latency caching for extremely hot keys
• your app is not Ruby on Rails
• you require advanced Redis features like pub/sub or distributed locks from your cache
