What are zombie requests in microservices?

Timed-out upstream requests where downstream services keep processing blindly, wasting resources.

How does Resile implement distributed deadline propagation in Go?

Via context.Context budgets injected into HTTP/gRPC headers, plus early-abort thresholds to kill hopeless calls.

Does Resile work with gRPC and HTTP?

Yes—natively supports Grpc-Timeout and custom headers, transport-agnostic.
