Hi Ben, I have a doubt. Can you please advise?
Hi, I have a situation in which there will be multiple instances of my graphql subscription server running. Data is coming over from a different data source let's say, Kafka. As soon as data reaches my server, I'll publish it to Redis pubsub.

So, if there are multiple clients connecting to different pods/instances of my server application. Will this ensures that all the instances will get the same data as soon as we publish something to Redis over the same topic?
(I'm in doubt here because there'll be a new instance of RedisPubSub in each of the pod)

Also, if suppose one of the pod goes down and the client reconnects, by that time client might lose some data, how can I prevent this data loss in this case?

Thank you, Ben, for this video. I have a single question, Can one use deploy to AWS cloud function?

Nice video Ben! Heroku supports Redis, so that should be easy too implement too i think.

For a production environment having just one redis server for the PubSub engine should suffice? Or is it possible that at some point many redis servers are needed? Is it even possible to do this with this graphql-redis-subscriptions package?

Awesome! Would love to see a RN tutorial series too with redux saga and graphql.

When I tried to run command "redis-cli" in my node.js app, nothing happens...I am on windows 7 and have used msi installer from MSArchive/3.2 release with default configurations and set the path variable too. Could you please help me out here, Ben ? BTW, awesome tutorial.. Truly awesome !

But why redis? The messages are saving on the SQL database... I don't get why you're use redispubsub :/
