Confluent - Developer for Apache Kafka Study Guide

1: Apache Kafka Fundamentals

This chapter grounds the developer view of Apache Kafka in the runtime facts that every producer, consumer, and Streams application depends on: how a broker cluster is organized under the KRaft controller quorum, how partitions and offsets encode ordering, how replication and ISR determine durability, and how records physically move from a producer through the log to a consumer. Every configuration key introduced here reappears in later chapters, so precise vocabulary matters more than breadth.
