SignalR groups in redis backplane

Making SignalR work with Redis backplane is as simple as adding AddStackExchangeRedis("localhost:6379"); to AddSignalR in Startup.cs.

So when I add a connection to a group in SignalR using this.Groups.AddToGroupAsync(connectionId, groupName);, Redis will also keep track of my group, right?

Is it possible to know when a new group is added to Redis or removed? An event or something? Or is it possible to programmatically check if a group exists? I'm Redis newbie.

Solution

  • Yes, it is possible to do what you want. You can start reading this documentation about Redis & SignalR.
