This glossary covers key Kafka terminology. For detailed explanations of each term, refer to the Concepts section. Terms are sorted alphabetically, with cross-references to related terms.

TL;DR

Core Components: Topic (logical channel), Partition (parallel processing unit), Broker (server), Producer (publisher), Consumer (receiver)

Reliability: ACK (delivery confirmation), ISR (synchronized replicas), Replication Factor (number of copies)

Consumer Management: Consumer Group (parallel processing), Offset (position), Commit (save), Rebalancing (redistribution)

Spring Kafka: KafkaTemplate (Producer), @KafkaListener (Consumer)

Metadata Management: KRaft (recommended for new clusters), Zookeeper (legacy)

This section compiles additional resources for learning Kafka. From official documentation to books, online courses, communities, and tools, we’ve gathered resources for systematic learning.

TL;DR

Official Documentation: Apache Kafka, Spring Kafka, Confluent docs are essential

Beginner Books: “Kafka: The Definitive Guide”, “Kafka in Action” recommended

Online Courses: Confluent Developer (free), Udemy, Inflearn

Communities: Stack Overflow, Confluent Forum, OKKY

Tools: Kafka UI (management), Prometheus+Grafana (monitoring)

Official Documentation#

Apache Kafka

Apache Kafka official documentation provides the most accurate and up-to-date information. Apache Kafka Documentation covers Kafka’s complete architecture, configuration, and APIs. Kafka Quickstart is the official Quick Start guide for beginners, covering installation through basic message sending/receiving. Kafka APIs provides detailed references for Producer API, Consumer API, Streams API, Admin API, etc. Kafka Configuration includes a complete list and descriptions of all configuration options for Broker, Producer, Consumer, Topic, etc.

This section compiles frequently asked questions and answers about Kafka. Organized by topic from basic concepts to configuration, error handling, performance tuning, operations, and Spring Kafka.

TL;DR

Basic Concepts: Kafka is a distributed event streaming platform, not a message queue; order is guaranteed per Partition

Configuration: Use acks=all for safety, auto.offset.reset=earliest recommended, manual commit to prevent message loss

Error Handling: Use @RetryableTopic for retries then move to Dead Letter Topic

Performance: Producer - batch/compression; Consumer - increase instances and adjust fetch settings

Operations: Recommend replication.factor=3, min.insync.replicas=2

Spring Kafka: Simple implementation with KafkaTemplate and @KafkaListener

Q: Is Kafka a message queue?
