CKafka instances are divided into Standard Edition and Pro Edition according to their specifications. The differences between the two editions are as follows:
|Items||Pro Edition||Standard Edition|
|Instance type||Dedicated instance||Shared physical node resource|
|Bandwidth specification range||Up to 10,000 MB/s. For more information, please see Billing Overview||Up to 150 MB/s. For more information, please see Billing Overview|
|The topic/partition capacity is much larger than that on the Standard Edition under the same bandwidth.
|Scalability||Its scalability is high, and the upper limits of bandwidth, topics/partitions, and disks can be increased separately||Its scalability is low, and its disk can be expanded separately|
|Automatic disk cleanup||Available. Expired data is cleared automatically||Unavailable. You need to submit a ticket|
|Broker repair and upgrade time||Quick upgrade||Subject to shared cluster resources, it takes a long time to upgrade|
|High availability||Custom multi-AZ deployment in the same region is supported to improve the disaster recovery capabilities||Multi-AZ deployment in the same region is not supported. It relies on backend migration and requires you to submit a ticket to apply, which generally takes 10 business days for processing|
|Technical support||Parameter optimization consulting services are supported, helping you customize parameter configurations for certain special business scenarios. You can submit a ticket to apply||Basic troubleshooting and problem fixing|
The automatic disk cleanup feature is enabled for the Pro Edition by default. When the instance disk is full, the oldest data will be automatically cleared to ensure that the instance is available.
