Kafka : Ordering Guarantees


Unique Partition Ordering

Physically topics are split into partitions. A partition lives on a physical node and persists the messages it receives.

Internal Retry Process

Kafka has an internal retry process :

Many Partitions ordering

Having one partition is cool (and sometimes depending of your business mandatory), but you will be obliged to have only one consumer, and the producer throughput will be limited. Thanks to the kafka system of key/partitions, you can create a more intelligent structure, that will allow you to have many partitions and continue having ordered messages.
