![]() Kafka Connect allows you to copy data between Kafka and other systems seamlessly: JDBC, JMS, Elasticsearch, and Amazon S3, just to name a few. If you want to move data around in a production fashion, please check out Kafka Connect. We advise against downloading messages for more than what you see on the Control Center UI (10–50 messages). Instead, it should be used for one-off downloads. It is crucial to note that you should not use this feature for production purposes. For example, download a handful of messages from within Control Center for manually inspecting the messages produced by KafkaProducer, for manually inspecting new schemas being applied to messages, or for aiding troubleshooting any Kafka message-related errors in Control Center. This is a simple yet effective tool if you are working with KafkaProducer, Confluent Schema Registry, or Control Center.
