Configure Redis for Roots Acorn by defining CACHE_DRIVER, SESSION_DRIVER, and REDIS_HOST environment variables alongside a Lando redis service, separating Redis databases for cache versus sessions to ensure durable cross-request performance.

Redis object caching solves fragile in-memory or filesystem storage by enabling a persistent wp_cache_* drop-in, ensuring your WordPress cache survives across requests for improved cross-request performance and atomic coordination.

Yes, you can use a Lando redis-cli service with Acorn queue drivers by configuring a Lando cache Redis service and setting the queue driver to Redis for durable background job execution and atomic coordination.

Your Acorn Redis cache connection gets refused when environment variables like REDIS_HOST are misconfigured or the Lando redis service is missing, requiring operational verification like a PING test to validate connectivity and debug driver failures.

Yes, you need separate Redis databases for Acorn sessions and WordPress object cache to prevent data collisions, ensuring cache tag-based invalidation and session persistence operate independently without overwriting each other.
