Thoughts on Topic Replication in Kafka

Jeffrey Carter elaborates on a pair of concepts related to topic replication in Apache Kafka:

Apache Kafka has the default ability to allow a topic to be created on a broker when a message is written to it and when a topic with the name the message is attempting to be written to does not exist. This can be very helpful in early development or prototyping where code, topic names, and schemas are in flux. However, past that early stage, it is recommended that Kafka be configured to disable the auto-creation of topics from messages for a few reasons. In this article I am going to touch on two of these reasons that are also core principles of Kafka partitions and Kafka topic replication.

Read on to understand what partitions and replication factor have to do with all of this.
