I read the documentation about scalling n8n but I still have a question.
In the documentation it mentions :
When running in queue mode you have multiple n8n instances set up (as many as desired or necessary to handle your workload), with one main instance receiving workflow information (e.g. triggers) and the worker instances performing the executions.
My question is about the “one main instance”. Does that means that we can’t have a high avaibility for this main instance ?
My company want to make a simulation of a loss of a datacenter so I need to have a backup is that possible ?
You can only have one main instance running but there is no reason as to why you couldn’t have it in an active passive setup and bring up the second main instance when the first one fails. As long as you have the same config options set for both and the database is replicated it should just be a case of making sure one is stopped and starting the other up.
