Overview

CKafka supports automatic adjustment of the disk utilization. After the disk utilization reaches the threshold, you can set the Dynamic Message Retention Policy to reduce the message retention time or set the Automatic Disk Capacity Expansion to adjust the disk space.

• Dynamic Message Retention Policy: After you set the message retention time, expired messages will be deleted. In case of message surges, normal production and consumption cannot be performed after the disk is full. If you set a dynamic retention policy, when the disk utilization reaches a certain percentage, a certain proportion of data will be automatically expired to avoid the above issue.
• Automatic Disk Capacity Expansion: When the disk load gets heavy, messages cannot be produced and consumed normally. After the automatic disk capacity expansion policy is set, when the disk load reaches the trigger threshold, the disk capacity will be automatically adjusted according to the policy, thus avoiding this problem.

Note

You can enable either dynamic message retention or automatic disk capacity expansion at any time.
