Considerations
The I/O specifications for each category indicate the I/O specifications of the tenant in terms of percentages. The format is: category_name: min_percent, max_percent, weight_percent. Separate the specifications of different categories with a semicolon. If a category is not specified, it is represented by other.
The sum of the min_percent values for all categories, including other, is 100, and the sum of the weight_percent values is 100.
Examples
The following example shows how to specify the percentage of I/O requests for each category for a tenant:
obclient> ALTER SYSTEM SET io_category_config = 'user: 30, 90, 50; log: 30, 90, 30; sys: 10, 10, 10; other: 30, 100, 10;';
