How to connect to multiple clusters in the same client?

[eb2tech]

Prior to v7.x, we were able to use a ClientBuilder to concurrently connect to multiple clusters. How is this best achieved now that ClientBuilder has been removed in v7.x?

Thanks,

It's similar in 7.x. Think of it as the ClientBuilder being unbundled from the HostBuilder.

For each client, you would create a new HostBuilder and then add the client to it

Let me see if I understand. Our 3.x implementation essentially had a dictionary of IClusterClients, keyed by cluster name. If a request for a cluster was made and an IClusterClient didn't already exist, one would be created using a ClientBuilder. With 7.x, we should create a HostBuilder instead, AddOrleansClient to it, and request the configured IClusterClient from the set of services built for that Host, adding that IClusterClient to the dictionary?

Or start with the existing IServiceCollection? (I admit I'm still learning how to use the new host extension mechanisms. The company I work for is just making the move to net6.0+.) I think I have something to start with.

One other caveat is that a silo in, say, cluster A, needs to act as a client to cluster B. A sample demonstrating how this would work under 7.x would be greatly appreciated.
