Add Missing Production Databases for Solid Queue and Solid Cache

[umarhadi]

The app failed to boot on Fly.io because Rails 8 expected separate queue and cache databases in production, but the MySQL config only defined primary and cable.

Root Cause

Rails 8 uses Solid Queue and Solid Cache in production, and both require their own database connections. The MySQL config didn’t include queue or cache entries for the production environment.

Fix

Added queue and cache database definitions to config/database.mysql.yml under production, matching the existing SQLite setup.

Production databases now include:

• fizzy_production
• fizzy_production_cable
• fizzy_production_queue
• fizzy_production_cache

Development and test remain unchanged because they don’t use database-backed queue/cache.
