What is Sidekiq Pro's behavior if Redis goes down?

[Ian Whitney]

We're moving from having Redis running on localhost to an external, hosted Redis solution. As part of this I now have to worry about what happens if the external Redis service becomes unavailable. Is this a case that Sidekiq Pro already handles well, or is this something where I should write some failover code?

Thanks,

Ian

Hi Ian, have you read through the Pro Reliability pages?  They talk about the features you can enable to handle network issues.  There is nothing in Sidekiq that will deal with failover to another server, it’s assumed the Redis client handles that transparently.

Thanks,

That page helps me understand the fetch side of things. But what about the client side?

Some background. Yesterday a simple configuration error managed to bring down the internet at my work. Fun! That outage led me to wonder what happened to jobs that my various Sidekiq clients tried to push into the queue during that time.

Reliable push is the client side.
