Confluent - Developer for Apache Kafka Study Guide

2: Apache Kafka Application Development

This chapter builds producer and consumer applications against Apache Kafka at practitioner depth, tightening every configuration knob introduced in the previous chapter into concrete Java and Python code patterns. It covers the durability, ordering, and throughput trade-offs of the client APIs, the three delivery semantics and how idempotence and transactions realize exactly-once processing, and the Schema Registry contract that keeps producers and consumers wire-compatible across schema evolution.
