Topic management

Kafka's distributed system uses a topic and partition model to organize data.

Topic is the principle of grouping a thread of posts into categories. A topic can be handled independently by multiple producers and consumers who have been granted access to it.

Sections⁠

Each top can have multiple partitions, which are physical storage units. Partitions are used for parallel data processing and system scaling. Each post is written to a specific section of the topic. All posts within the same section retain their order.

When create-topic you can define the number of sections in the topic. Once the cluster is created, you can only increase the number of tops.

Create a topic⁠

  1. In Control Panel, go to Cloud Platform → Databases.
  2. Open the cluster page → Topics tab.
  3. Click Create Topic.
  4. Enter a name for the topic.
  5. Enter the number of sections. The maximum number of sections is 4,000. You can't reduce the number of partitions once you create a topic.
  6. Press Create.
