Stream Message Resource

A Stream Message is a JSON message that can be sent at a high rate to an elastic group of subscribers.

  • Messages are ephemeral - they can be published (created), but they cannot be queried, updated or deleted
  • The maximum Message payload size as serialized JSON is 4KB.
  • The maximum Message publishing rate per Stream is 30 per second.
  • Message delivery to remote endpoints is not guaranteed.
  • Messages may be received by remote endpoints in a different order than they were published.
