ZooKeeper-free Kafka is out. First Demo

> Yeah! I mean, I find a lot of linearizability errors in various databases, but this was also my very first time doing this kind of test, and it varies from system to system. Could have easily slipped through the cracks.

Looks like Zookeeper needs to be tested again.

For reading headers from the command line, KIP-431 adds support for optionally printing headers from the ConsoleConsumer, which will be available in the Apache Kafka 2.7.0 release.You can also use kafkacat to view headers from the command line. Here’s an example command:
