15 kcat is a generic non-JVM producer and consumer for Apache Kafka 0.8,
16 think of it as a netcat for Kafka.
17
18 In producer mode ( -P ), kcat reads messages from stdin, delimited with a
19 configurable delimeter and produces them to the provided Kafka cluster,
20 topic and partition. In consumer mode ( -C ), kcat reads messages from a
21 topic and partition and prints them to stdout using the configured mes‐
22 sage delimiter.
23
24 If neither -P or -C are specified kcat attempts to figure out the mode
25 automatically based on stdin/stdout tty types.
26
27 kcat also features a metadata list mode ( -L ), to display the current
28 state of the Kafka cluster and its topics and partitions.
29
31 For a more extensive help and some simple examples, run kcat with -h
32 flag.
