Describe the problem/error/question

Hi Team,

Could you please help clarify a few things regarding Redis Sentinel support for N8N?

Q1: Does N8N support Redis Sentinel? If yes, what configuration changes are required in the startup arguments or environment variables?

Q2: Can the QUEUE_BULL_REDIS_HOST environment variable accept multiple hosts (e.g., redis.host.v1:1234,redis.host.v2:1234) to support high availability with Sentinel?

We’re currently using a standalone Redis instance but planning to migrate to Sentinel. We’d like to understand the flexibility and required setup for this.

Thanks in advance for your support!

What is the error message (if any)?

Hi,

I would doubt it tbh. a similar feature request is open for adding multiple postresql servers via connection string.

You can always log a feature request here, but the implementation depends on the number of votes.
