Does one GRPC channel request generate one more new thread in the GRPC server side?

To fix this issue There may be up to one Runnable enqueued to the Server's executor for application processing. Each request may generate more than one Runnable over time, but only one at a given time. The default executor is an unbounded cached thread pool, so worst-case each request gets its own thread initially, but later requests will generally reuse previous threads.
It is good practice for high QPS services to specify a fixed-sized executor, to avoid excessive number of threads and reduced context switch thrashing.

Can we reliably log the result of every gRPC call to our grpc-java server?

hope this fix your issue You want ServerCall.Listener.onComplete() and ServerCall.Listener.onCancel(). onComplete() is called after ServerCall.close() is processed successfully. onCancel() is used for any communication error or cancellation. Note that it is possible to receive onCancel() after the application calls ServerCall.close().
