    Hi All,

    I am able to understand the notification pattern in design guidelines. How ever, I am not able to understand the concept of topic/event. It would be very helpful if the forum could explain events related to topics and their relation with notification pattern with use-cases.

    Thank you.

    Best regards,

    Hi Kalpana
    This is part of the Event API (swagger available at early access page here). The Event API provides an alternative to the older hub-based (point-to-point) publish and subscribe pattern, by abstracting the functionality of a message broker (such as the Apache Kafka project, RabbitMQ, queue managers on public cloud such as AWS SQS and equivalents, and many other commercial offerings).
    Typically a message broker allows you to define a set of queues, or topics. Message producers (publishers) write events (messages) to topics, and consumers (subscribers) read from these topics.
    Hope it helps
