Render Key Value

Render Key Value provides low-latency, Redis-compatible in-memory storage running Valkey 8. Use it as a shared cache, session store, or job queue backend. Compatible with virtually all Redis client libraries.

When to Use

• Adding a cache or session store to a web app
• Wiring a job queue backend for Celery, Sidekiq, BullMQ, Asynq, or Oban
• Choosing the right maxmemory policy (cache vs queue)
• Configuring ipAllowList in Blueprints (required field)
• Connecting via internal vs external URLs
• Troubleshooting auth failures or connection refused errors

For background worker setup and queue framework patterns, see render-background-workers. For Blueprint authoring, see render-blueprints.

Before configuring or troubleshooting an internal Key Value connection, read references/private-networking.md.
