Apache Kafka

A distributed event streaming platform that stores ordered, durable, replayable logs of records in partitioned topics.

Definition

Producers write to topics, brokers store partitions with replication, and consumers in groups read in parallel while tracking offsets. Kafka provides high throughput and retention-based replay. Managed options include Amazon MSK, Confluent Cloud and Event Hubs' Kafka endpoint.

Exam tip

Ordering is guaranteed only within a partition, not across a topic.
