Topic

Represents topic, that asynchronously exchanges messages between one or more publisher(s) and one or more subscriber(s).

Guarantees: - Order of messages from publisher is guaranteed to be preserved to all subscribers - Messages from publishers may interleave in non deterministic order before they are read by subscribers - Once the subscriber is run it will receive all messages from all publishers starting with very first message arrived AFTER the subscriber was run

Please note that topic is active even when there are no publishers or subscribers attached to it. However once the close or fail is called all the publishers and subscribers will terminate or fail.

Once topic if closed or failed, all new publish or subscribe attempts will fail with reason that was used to close or fail the topic.
