Scenario
A Kafka instance is a concept of Kafka message queuing system. In Kafka, an instance represents a separate Kafka cluster. It contains a set of Kafka brokers that work together to provide high availability and scalability. Each instance has a unique identifier that can be used to distinguish between instances in the cluster. An instance can contain multiple topics, and can be configured with a different number of partitions and replicas. By creating multiple instances, you can implement multiple independent Kafka clusters to meet different business requirements.
Procedure
(1) Log in to the management console.
(2) Enter the Kafka management console, where you can see the current instance list, as shown in the following figure.
(3) There are two types of Kafka engines: cloud-native and Kafka.
l Cloud-native engine: Fully compatible with the open-source Kafka ecosystem, less I/O bandwidth occupation and able to handle higher performance peaks.
l Kafka engine: Large-scale partitions with more stable performance, and no data migration required for capacity expansion.
(4) On the page, the purchased Kafka instances are listed and you can view their status, which is described as follows:
Status | Description |
Running | The instance is running properly. Instances in this state can provide services. |
Closed | The instance is not running properly. |
Changing | The instance specifications are being changed. |
Change failed | The instance specifications failed to be changed. |
Pause | The Kafka Exclusive Edition instance is frozen. You can renew the Kafka instance in More. |
Canceled | The Kafka instance has expired and is shut down. You need to purchase a new instance. |
