The right way of hosting worker threads on each rounded hour RRS feed

  • Question

  • User-375835195 posted

    Hi,

    I'm making an application which is supposed to have multiple threads/services (bots) running. Those threads are supposed to check an API for current currency values. There will be some calculations on each rounded hour (e.g. 10:00, 11:00, etc).

    Currently, I'm running Angular (front-end) and ASP.NET Core 2.2 MVC + SignalR (back-end).

    What's the right way of hosting those threads/services? Assuming those threads are spawned based on database records.

    I was looking at https://docs.microsoft.com/en-us/aspnet/core/signalr/background-services?view=aspnetcore-2.2 but I'm not quite if that's the right solution since I have to display the results in the front-end with SignalR if they match to certain conditions.

    What's the right way of doing that scenario?

    when using background services, you use Scope when you are using DI and you need a new instance. This is unrelated to the scope created for web requests. 

    you should be looking at the queued sample. your signal/r client should queue a timer request. the background process should be running on a timer. every time it hits the clock cycle, it should check the queue / collection and process the queue / collection (starting threads if required). you will then need a determine when to stop processing and remove the queue / collection.
