Nope. Better to generate it yourself if you need it immediately.

The Thrift IF predates vnodes. I agree that's a reasonable alternative.

Given a unit and a system test that cover the same code, the unit test is
10x more useful when something breaks. It's difficult to run dtests locally
at all, let alone attach your debugger to the right instance at the right
time to troubleshoot deeper.
So my preferred approach is, unit test when p

Update:
I'm planning to send out confirmations for half of the seats at the

there's a number of examples in the tests where we converted from the old

I've talked to a dozen plus using LOCAL_SERIAL.
I could try to get more exact numbers if it would help but back of the

that is a very good design, as you would no longer get any of the benefits
of the deterministic approach you started with. If you mean something
else, then perhaps an example would help clarify.
