Message topics are a concept in message processing that allows messages to be categorized into topics or subjects and sent to various recipients interested in a specific topic.
In the context of message brokers or messaging services, topics enable the publication of messages related to a particular theme or category. These messages can then be received by multiple subscribers or recipients interested in that topic by subscribing to it.
A publisher, responsible for generating messages, sends a message to a specific topic, and multiple subscribers can receive these messages by subscribing to or registering interest in that topic. This topic-based communication allows for flexible, scalable, and targeted message distribution in distributed systems or applications.
For instance, a message topic could be 'Technology,' and all messages associated with this topic would be sent to subscribers interested in technology, while other subscribers interested in topics like 'Sports' or 'Science' would only receive messages related to those specific themes.
