Theory ------------- ✅ Kafka Core Concepts: Brokers, Topics, Partitions, Offsets & More 🟢 Kafka Broker A Kafka broker is a server that stores and delivers messages. A Kafka cluster consists of multiple brokers for load balancing & fault tolerance. Brokers store messages in topics and handle consumer-producer interactions. 🟢 Kafka Topics Topics are logical categories where messages are published. A producer sends messages to a topic, and consumers subscribe to it. Topics can have multiple partitions to improve parallel processing. 🟢 Kafka Producer & Consumer Producers send data to Kafka topics. Consumers read data from topics asynchronously. Consumers subscribe to topics and process messages in real time. Kafka provides consumer groups to distribute load among multiple consumers. 🟢 Kafka Partitions Kafka splits topics into multiple partitions to scale horizontally. Each partition is stored on different brokers, allowing parallel processing. Data is ordered within a partition but unordered across partitions. 🟢 Kafka Offsets Offsets track message positions within a partition. Each message has a unique offset number to ensure consumers read messages sequentially. 🟢 Kafka Message Keys Kafka message keys decide which partition a message is stored in. 🟢 Kafka Serialization Messages in Kafka are stored as bytes. Serialization formats: JSON, Avro (efficient for schema evolution), Protocol Buffers. 🟢 Kafka Consumer Groups Multiple consumers can read from the same topic in parallel. Consumers in the same group share partitions for better load balancing. Each partition is assigned to only one consumer per group. 🟢 Kafka Cluster A Kafka cluster consists of multiple brokers working together. Clusters provide high availability & fault tolerance. Data is replicated across multiple brokers for reliability. 🟢 Kafka Zookeeper Zookeeper manages metadata and leader election in Kafka. Stores broker information, partition leader details, and consumer offsets. 🟢 Kafka KRaft (Kafka Raft) KRaft (Kafka’s built-in consensus protocol) replaces Zookeeper.
