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 an 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.
