This post will teach you how to use the Confluent Python client with Simple Authentication and Security Layer Mechanisms (SASL)/OAUTHBEARER security protocol to produce and consume messages to topics in Apache Kafka and use the service registry to manage the JSON schema.
SASL/Oauthbearer is more secure than SASL/PLAIN where the username/password is configured in the client application. In case user credentials are leaked, the blast radius would be more significant as the user might have other access. In SASL/OAUTHBEARER, service accounts are preferred, which reduces the blast radius on leakage. It is recommended to have one service account per client application. With service accounts, resetting credentials can be quickly compared to user credentials.
