Create a Kafka Topic

Some of the content described in this article is available in meshIQ Manage versions 11.1.1 and later. See meshIQ platform Highlights v11.1 for an overview of feature changes.

You can create a Kafka topic from a topic viewlet in one of two ways:

  • Select Create Topic from the Action menu (called the Selected menu in 11.2), when a topic is selected in a Topic viewlet.
  • Click the Add AddBt.png button for a Topic viewlet. 

Create a Kafka topic

To create a topic:

  1. If you clicked the Add AddBt.png button, the Select object path window opens.

  4. Fill in the topic properties (Topic Name is a required field). The Configuration tab is empty during the create process, but is filled in and can be edited when the topic has been created (see the editing instructions below). You can also create your own properties on the Custom Attributes tab.  
  5. Click OK to create the topic. See Edit a Kafka topic below for information about properties that become available once a new Kafka topic is being edited.

Edit a Kafka topic

To edit a Kafka topic:

  1. Select the checkbox for the topic and select Properties... from the action menu (Selected menu in 11.2). The Kafka Topic Properties dialog opens. The following additional fields are now present: Is Internal, Preferred Leader Replicas, Replicas not in sync, Consumer Groups, Compression Type, Minimum In-sync Replicas, Cleanup Policy, Bytes per Segment, Retention (ms), Max Message Size (bytes), Unclean Leader Election, Retention (bytes). Refer to Kafka Topic field descriptions for more information.

  2. Make your changes on the General tab. If you choose to increase the number of partitions, you will not be able to roll back the change later, since decreases in the number of partitions are not permitted. When browsing partitions from a topic, both the System and the Empty checkboxes are selected on the Partitions viewlet, so that all partitions are displayed, and empty ones are included.
  3. On the Configuration tab, properties are now available for editing. Use the Configuration Entry (Filter by key) and Value (Filter by value) filters to find the configuration entry you want to update. Make your changes by replacing the existing values with new values.
