Solid Cache configures Rails to use a separate database as a cache store instead of in-memory storage. Enable it in production by setting config.cache_store to use Solid Cache, configure multi-database setup to point to your cache database, and Rails will persist cache entries with automatic expiration and compression.

Solid Cache supports per-entry expiration and fetch-with-expiration patterns for hierarchical key designs. Set TTL on individual cache writes or use fetch blocks that auto-expire, enabling flexible strategies from short-lived session data to long-lived computed results without manual invalidation.

Yes, Solid Cache implements hierarchical and Russian doll key patterns natively. Nested cache keys automatically expire parent entries when child entries change, reducing the need for manual cache invalidation and simplifying complex dependency management.

Enable ZSTD compression to reduce database storage and I/O, use batch operations for bulk reads and writes, and run routine VACUUM maintenance tasks to reclaim space. These tuning steps significantly reduce database load and improve cache hit latency at scale.

Solid Cache is database-backed and benefits from NVMe-backed database storage through faster I/O. While the Skill configures the caching layer, NVMe hardware acceleration occurs at the database level and can improve throughput for high-frequency cache operations.

Solid Cache requires periodic VACUUM maintenance tasks to reclaim space from expired and deleted cache entries. Routine maintenance prevents database bloat, maintains query performance, and is part of standard production operations for database-backed cache stores.
