kafka consumer specified output

Question

I read that in kafka docs: Kafka also has a command line consumer that will dump out messages to standard output.

bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning

I wonder that if I want to consumer messages and push them to another output, what options to be add to the above command. kafka-console-consumer does not have --help option, I can't find any parameters, options for command.

Thank you

The default consumer can only output to console, unless you would want to download and modify the code.

It's very easy to write a simple consumer and output to other format or do something else with it.

A sample code is listed at https://cwiki.apache.org/confluence/display/KAFKA/Consumer+Group+Example
