May 1, 2024 3 minute read

CloudEvents is a specification for describing event data in a common way, regardless of the source of the event or the technology used to transmit it. CloudEvents provides a common format for describing the metadata associated with an event, such as the event type, source, and time, as well as the payload of the event. This allows events to be easily exchanged between different systems and applications, regardless of their underlying technology.

  • ID: A unique identifier for the event.
  • Source: The producer of the event.
  • Type: The type of event.
  • Subject: The subject of the event.
