%description
    Jocko is a re-implementation of the Kafka distributed commit-log
    service in Go. It is protocol-compatible with Kafka, so Kafka
    clients and services work with Jocko. But Jocko is easier to operate
    as it does not depend on Zookeeper and instead uses Serf and RAFT
    internally.
