kafka-offset-setter

CLI tool for changing the last consumed offset of a Kafka consumer.

Example usage

Our consumer is defined in kafka.properties and we want to set the offset to 12345 in the topic MY_TOPIC, partition 2. Just issue the command:

java -jar kafka-offset-setter-0.0.2.jar -t MY_TOPIC -p 2 -c kafka.properties -o 12345

Expected output:

Creating Kafka consumer ...
Committing offset 12345 to topic MY_TOPIC, partition 2 ...
Closing Kafka consumer ...
Done!

Next time you will start your consumer, it will start at offset 12345.

If you don't supply the option -o, then the program will just connect to Kafka and otput the current offset for the group.id.

You also have the possibility to supply properties for the Kafka consumer inline with -i

java -jar kafka-offset-setter-0.0.2.jar -t MY_TOPIC -p 2 -i "group.id=my_group_id" -i "client.id=my_client_id"
