This document describes how to create a topic under an existing instance in the CKafka console.
2. On the Instance List page, click the ID/Name of the instance created in Step 1. Create an Instance to enter the instance details page.
3. On the instance details page, click Topic Management at the top of the page, and click Create.
4. In the Create Topic dialog box, set parameters as needed.
Name: The topic name. It cannot be changed once entered and can contain only letters, digits, underscores, or symbols ("-" and ".").
Partition Count: It is a concept in physical partition, where one topic can contain one or more partitions. CKafka uses partition as a message allocation unit.
Replica Count: The number of partition replicas is used to ensure the high availability of the partition. To ensure data reliability, creating a single-replica topic is not supported. Two replicas are enabled by default.
Replicas are also counted into the number of partitions. For example, if you create 1 topic with 6 partitions, and 2 replicas for each partition, then you have a total of 12 partitions (1 x 6 x 2).
Tag: Set a resource tag. For more information, see Tag Overview. Preset ACL Policy: Select the preset ACL policy. For more information on ACL policy, see Configuring ACL Policy.
