I have set up the Azure SignalR Service for REST API. There are three modes under settings: Default, Serverless, Classic. I can't find any information about what each of these items sets. The only one thing I got so far, that if I use Azure SignalR for Azure Functions or REST APIs it's preferable to use Serverless option.
From documentation:
Change the Service Mode setting to Serverless only if you are using Azure SignalR Service through Azure Functions binding or REST API. Leave it in Classic or Default otherwise.
Serverless mode is not supported for ASP.NET SignalR applications. Always use Default or Classic for the Azure SignalR Service instance.
Could you please help me to find what each of these options sets?
