Hermes v0.15.9 Release Notes

  • ๐Ÿ”‹ Features

    (996) Attaching HTTP headers with subscription identity

    โž• Added subscription flag subscriptionIdentityHeadersEnabled. When you set it to true, then Hermes for each message send to subscriber will attach headers like Hermes-Topic-Name, Hermes-Subscription-Name. Thanks to this headers subscriber can verify whether message comes from expected topic and subscription. ๐Ÿ”’ This feature is related to security.

    (995) Consumer groups in console

    Subscription view in Hermes-console received new panel called Diagnostics. The panel contains only single button redirecting to consumers-group endpoint. It reveals internal information about Kafka topic, for example current offset, lag or which consumer is attached to which partition. These kind of information sometimes are helpful for Hermes administrator to analyze subscription. So for we read them manually via Kafka scripts, now we can use consumer-group endpoint which is much simple way.

    The view of Diagnostics panel is very basic now, in the future we can improve it.
