Solid Cache is Rails 8's default cache backend—a database-backed cache store using NVMe storage instead of RAM. It eliminates the need for Redis/Memcached while providing FIFO eviction.

| Choose Solid Cache When | Choose Redis When |

| Simplifying infrastructure | Sub-millisecond latency critical | | Using PostgreSQL/SQLite as primary | Extremely large cache working set | | Single-server or small clusters | Need pub/sub or complex invalidation | | Preferring NVMe over RAM caching | Already running Redis |

在配置或使用 Solid Cache 进行数据库支持的缓存时使用。应用 Rails 8 约定、缓存键设计、过期策略、数据库设置和性能调整模式。 来源：majesticlabs-dev/majestic-marketplace。
