Database-backed cache store for Rails — replaces Redis/Memcached with SQL database (SQLite, PostgreSQL, MySQL) for Rails.cache. Solid Cache features: ActiveSupport::Cache::SolidCacheStore adapter, automatic LRU-style expiry via background trimming, configurable max_age and max_size limits, encryption support via Active Record encryption, multi-database support (dedicated cache DB), expiry worker process, and Rails 8 default cache store for apps without existing Redis. Eliminates Redis operational overhead for agent apps that use caching only for Rails.cache — session data, fragment caching, low-churn data.
