Learn how to use the
kafka-console-consumer tool can be useful in a couple of ways:
- Acting as an independent consumer of particular topics. This can be useful to compare results against a consumer program that you’ve written.
- To test general topic consumption without the need to write any consumer code.
Examples of usage:
kafka-console-consumer --bootstrap-server [BROKER1],[BROKER2]... --topic [TOPIC] --from-beginning [record-earliest-offset] [record-earliest-offset+1]
Note the following about the tool:
- This tool prints all records and keeps outputting as more records are written to the topic.
- If the
kafka-console-consumertool is given no flags, it displays the full help message.
- In older versions of Kafka, it may have been necessary to use the
--new-consumerflag. As of Apache Kafka version 0.10.2, this is no longer necessary.
