kcat

kcat is a generic non-JVM producer and consumer for Apache Kafka >=0.8, like a netcat for Kafka. In producer mode kcat reads messages from stdin, delimited with a configurable delimiter (-D, defaults to newline), and produces them to the provided Kafka cluster (-b), topic (-t) and partition (-p). In consumer mode kcat reads messages from a topic and partition and prints them to stdout using the configured message delimiter. There's also support for the Kafka >=0.9 high-level balanced consumer, use the -G <group> switch and provide a list of topics to join the group. kcat also features a Metadata list (-L) mode to display the current state of the Kafka cluster and its topics and partitions.
