Topic

Corresponds to the EBX® event type that contains messages. The number of subscribers registered to a topic is unlimited.

Subscriber

Client implementation in the modules that receive the events related to the subscribed topic(s).

Topics

Dataspace and snapshot

Corresponds to operations in the dataspace and in the snapshot, such as: create, close, reopen, delete, archive export and archive import (only for dataspace merge).
