For more details on the configuration properties, see Since Kafka Connect is intended to be run as a service, it also supports a REST API for managing connectors. ms = A plugin interface that allows you to intercept (and possibly mutate) the records received by the producer before they are published to the Kafka cluster. security. : 4: Name of the stream consumer group (default: kafka-consumer-group).
