Confluent - Administrator for Apache Kafka Study Guide

5: Apache Kafka Cluster Configuration

This chapter is the operator handbook for the configuration surface of an Apache Kafka broker fleet running in KRaft mode. It covers the broker and controller properties that shape durability, throughput, and network behavior, the internal-topic replication factors that must be raised on real clusters, the hidden broker load created by Kafka Streams and ksqlDB, compression policy at broker and topic level, static versus dynamic configuration precedence, topic administration, partition reassignment, offset administration through `kafka-consumer-groups --reset-offsets`, quotas, and the core `kafka-*` CLI surface an administrator uses daily.
