Hi Vladimir,

An event is generated when a publisher creates a topic to initiate the communication process in the pub-sub service. This event signals the system that a new topic has been created. It’s then sent to the pub-sub service, which filters and enqueues it to the relevant partition queue of the topic. This event generation is crucial as it triggers the notification service, allowing subscribers who have expressed interest in that particular topic to receive updates. Essentially, it helps in maintaining the real-time functionality of the pub-sub model, ensuring timely and efficient dissemination of information.

Thank you.
