kafkacat

Apache Kafka producer and consumer tool.

• Consume messages starting with the newest offset:

kafkacat -C -t {topic} -b {brokers}

• Consume messages starting with the oldest offset and exit after the last message is received:

kafkacat -C -t {topic} -b {brokers} -o beginning -e

• Consume messages as a Kafka consumer group:

kafkacat -G {group_id} {topic} -b {brokers}

• Publish message by reading from stdin:

 echo {message} | kafkacat -P -t {topic} -b {brokers}

• Publish messages by reading from a file:

kafkacat -P -t {topic} -b {brokers} {path/to/file}

• List metadata for all topics and brokers:

kafkacat -L -b {brokers}

• List metadata for a specific topic:

kafkacat -L -t {topic} -b {brokers}

• Get offset for a topic/partition for a specific point in time:

kafkacat -Q -t {topic}:{partition}:{unix_timestamp} -b {brokers}
