Ensuring Ordering of Kafka Data

Zeke Dean takes us through an explanation of Kafka partitioning and message delivery behaviors:

Apache Kafka provides developers with a uniquely powerful, open source and versatile distributed streaming platform – but it also has some rather complex nuances to understand when trying to store and retrieve data in your preferred order.

Kafka captures streaming data by publishing records to a category or feed name called a topic. Kafka consumers can then subscribe to topics to retrieve that data. For each topic, the Kafka cluster creates and updates a partitioned log. Kafka send all messages from a particular producer to the same partition, storing each message in the order it arrives. Partitions therefore function as a structure commit log, containing sequences of records that are both ordered and immutable.
