Competing consumers events not appearing - .NET API

EventStoreDB
1

Am I missing something here? No exceptions thrown, no events appearing.

        PersistentSubscriptionSettings settings = PersistentSubscriptionSettings
                                                    .Create()
                                                    .DoNotResolveLinkTos()
                                                    .WithReadBatchOf(1000)
                                                    .StartFromBeginning();

        _eventStoreConnection.CreatePersistentSubscriptionAsync(
                                                "$all",
                                                "sspevent",
                                                settings,
                                                _eventStoreCredentials);

        Console.WriteLine("Subscription group created.");

        _eventStoreConnection.ConnectToPersistentSubscription(
                                                "$all",
                                                "sspevent",
                                                (sub, evt) => EventAppeared(sub, evt),
                                                (sub, reason, ex) => SubscriptionDropped(reason),
                                                _eventStoreCredentials,
                                                1000,
                                                false);

$all isnt actually a stream, competing consumers only support streams
at this point in time.

We looked at doing the work for $all but as its just a performance
improvement (uses the readfromall methods etc) it was deemed
non-critical. We left it as work we would be happy to do later if
someone really needed it and wanted to pay for it.

Cheers,

Greg

Well that’s a tad disappointing.

That said, shouldn’t I get an error when creating the persistent subscription? There is no error on initial create. Also, nothing is thrown when I do it repeatedly without a delete in-between. Definitely should be more feedback here. It feels like a black hole presently.

I agree, will add an error on it. track issue here:
https://github.com/EventStore/EventStore/issues/1018 I added to 3.9.0
which is expected soon but it may be the next version after.

See: https://github.com/EventStore/EventStore/pull/1019 should be in 3.9.0

Thanks for the quick turnaround on that Greg!
