SASL_SSL
security protocol supported by Kafka is used.
To consume messages, you need a Kafka message consumer, proper consumer configuration, credentials, and your client system must trust the Let’s Encrypt trust chain. The consumer configuration includes the URL of the EHA broker, the topic name, and the credentials. Topics are separated by subscription ID, and security policies ensure that only you can access your subscriptions.
Each topic you can receive notifications from is dedicated to a specific subscription. Therefore, you must request specific streaming client credentials for each subscription. Once you have collected all the streaming credentials for a subscription, you will be able to connect to all its associated topics.
SASL/OAUTHBEARER
authentication — a SASL-based mechanism for authenticating clients using OAuth tokens based on the JSON Web Token (JWT) standard, as specified in RFC 7519. You can use the SASL/OAUTHBEARER mechanism to authenticate your Kafka clients.
