Goals of this project:

  • Implement Kafka in Go
  • Protocol compatible with Kafka so Kafka clients and services work with Jocko
  • Make operating simpler
  • Distribute a single binary
  • Use Serf for discovery, Raft for consensus (and remove the need to run ZooKeeper)
  • Smarter configuration settings
    • Able to use percentages of disk space for retention policies rather than only bytes and time kept
    • Handling size configs when you change the number of partitions or add topics
  • Learn a lot and have fun
