Distributed commit log service in Go that is wire compatible with Kafka.
Created by @travisjeffery, continued by nash.
- Protocol compatible with Kafka so Kafka clients and services work with Jocko
- Distribute a single binary
- Use Serf for discovery, Raft for consensus (and remove the need to run ZooKeeper)
- Simpler configuration settings
- Map features missing
- Extensive protocol compliance test suit
- Update all dependencies and code to up-to-date Go (as of MAR2020)
- How Jocko's built-in service discovery and consensus works
- How Jocko's (and Kafka's) storage internals work
