Tuning workers performance

I am using sentry in production environment,but production environment has too many events send to sentry, that cause the events.preprocess_event queue too large,I have read the document,this is just solve the problem in one machine.So question is comming.

Can I start up more than one worker program to deal with events?
Does the worker program have a state?

Will it be useful to change from redis to rabbitMQ?
I don’t think the problem has something to do with redis,maybe I was wrong.

You can and definitely should run more than 1 worker process if you need it.

Thank you for your reply!
I think Sentry design very very good,The web and worker are stateless service.
