Overview
kcat is a generic non-JVM producer and consumer for Apache Kafka 0.8, think of it as a netcat for Kafka.
In producer mode ( -P ), kcat reads messages from stdin, delimited with a configurable delimeter and produces them to the provided Kafka cluster, topic and partition. In consumer mode ( -C ), kcat reads messages from a topic and partition and prints them to stdout using the configured message delimiter.
If neither -P or -C are specified kcat attempts to figure out the mode automatically based on stdin/stdout tty types.
kcat also features a metadata list mode ( -L ), to display the current state of the Kafka cluster and its topics and partitions.
