Two publishers of one track
Two publishers announce the same namespace and publish the same tracks, one with identical payloads and one with payloads that differ by publisher. Partway through, the publisher serving the subscribers disconnects without notice. A fresh subscription, sent afterwards, shows whether the remaining publisher could still be reached.
| Publisher | Role | Announcement | Subscribed to | Ended by the relay |
|---|---|---|---|---|
| first publisher disconnected | serving The relay accepted it and subscribed to it. | accepted, REQUEST_OK in 176 ms | differing payloads, identical payloads | — |
| second publisher | serving The relay accepted it and subscribed to it. | accepted, REQUEST_OK in 174 ms | differing payloads, identical payloads | — |

| differing payloads | objects with two payloads 15 of 42 with two payloads | first publisher, second publisher | carried on from the other publisher first object 192 ms after | — |
A fresh subscription after the publisher left: delivered, first object in 191 ms.
Delivered one Object with two different payloads on one subscription.
