Creating an Apache Kafka® topic

While you can set Apache Kafka® to automatically create a topic when the a message is produced to a topic that does not exist, creating topics beforehand is generally considered a preferred practice and recommended for production environments:

  • it lets you to define granular topic settings such as the number of partitions, the replication factor, the retention period and more.

  • It prevents the wrong topic being generated (for instance with typos).
