Kafka Guarantees

The video tutorial covers the essential guarantees provided by Kafka, focusing on message ordering and replication. It explains how messages are appended to topic partitions in the order they are sent and read by consumers in the same order. The importance of a replication factor is highlighted, allowing producers and consumers to tolerate broker failures. The tutorial also emphasizes maintaining a constant number of partitions to ensure message keys consistently map to the same partition. The session concludes with a recap of these key points.
