Apache Dubbo Component

Details

In Dubbo 3, when using Application-Level Service Discovery, for example, when I configure this snippet in my consumer yaml:

  ...
  consumer:
    provided-by: A,B,C

I want to achieve a purpose that I can specify the concrete service when invoke RPC call each time, such as I specify service C when invoke RPC call this time, and I specify service A when invoke RPC call for the next time.

Is there anyway to achieve my purpose? thx.

This is a good question. We don't have an elegant way to specify provided by in a large app.
