David Li commented on ARROW-15473:
----------------------------------
[~rteodorescu] just to be clear of a few things: are you talking about multiple
concurrent calls on the same client, and a way to cancel all of them at once?
That is indeed unimplemented. I'm not sure gRPC even gives us a way to do this;
you'd just have to track all your ongoing calls, and Cancel() all of them
(which to be fair is a bit of a pain especially once threading comes into play).
