Redis & OpenSearch for
Magento 2
Redis eliminates session file I/O while OpenSearch delivers instant catalog search. Together, they transform Magento's weakest points into competitive advantages.
Sessions and cache held in memory on separate instances, no disk I/O bottleneck or session locking at checkout.
OpenSearch powers storefront search and layered navigation, mandatory in Magento 2.4.
Redis
Redis stores session data and Magento's backend cache in memory, eliminating slow disk operations that plague default installations.
- Session storage (no file locking issues)
- Configuration cache (instant config loads)
- Default cache backend
- FPC tag storage
OpenSearch
OpenSearch (Elasticsearch-compatible) powers Magento's catalog search, layered navigation, and product recommendations with sub-second response times.
- Instant search suggestions
- Faceted navigation (filters)
- Handles 500k+ SKUs
- Adobe Commerce compatible
Running Magento 2.4.9? Valkey now replaces Redis
Adobe's official system requirements for Magento 2.4.9 list Valkey 9 as the supported cache and session store, and Redis is no longer on the supported list. Redis stays wire compatible, so existing configuration keeps working, but new 2.4.9 builds should be on Valkey. Search moves too: OpenSearch 3 is required and Elasticsearch is fully dropped.

Why This Stack Matters
Default Magento installations use file-based sessions and MySQL-based search. Both become severe bottlenecks at scale. Our Redis + OpenSearch stack eliminates these limitations.
