Kafka provides several message delivery semantics that allow producers and consumers to control the ordering, consistency, and reliability of message processing. Here are the different message delivery semantics in Kafka: 1. At most once: In this delivery semantic, messages are sent by the producer to Kafka, but there is no guarantee that they will be … Read more
Kafka uses message offsets to manage the state of message consumption within a Kafka consumer group. Message offsets are used to track the progress of each consumer in the group, ensuring that each consumer processes messages from the correct position within a Kafka topic. Here’s how Kafka handles message offset management: 1. Offset tracking: Kafka … Read more
Apache Avro is a data serialization system that is used in Kafka to encode data in a compact binary format that can be efficiently transmitted and processed by Kafka-based applications.
