Description

The gRPC API now has a way to get the "estimated delay" before a job will be complete: https://docs.api.qcs.rigetti.com/protobuf/#services.controller.EstimatedDelay

When the minimum delay is greater than the get-results gRPC timeout, the client will not be able to get the job results.

The SDK should automatically detect this situation (by requesting the job status either immediately after submitting a job, or automatically as part of requesting the job results), and it should permit the user to do either of the following:

  • cancel the job
  • re-request results with a sufficiently long timeout

Research direction

Start with the gRPC EstimatedDelay API and trace the SDK's job submission and get-results flows. Determine where job status is requested and how cancellation or a longer results timeout can be exposed; done means users can detect an insufficient timeout and either cancel or retry with a sufficient one.
