Considerations
The I/O specification for each category specifies the I/O specification ratio of the tenant. The format is category_name: min_percent, max_percent, weight_percent. Multiple I/O specifications are separated by semicolons. If a category is not specified, it is represented by other.
The sum of the min_percent values of 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:
obclient> ALTER SYSTEM SET io_category_config = 'user: 30, 90, 50; log: 30, 90, 30; sys: 10, 10, 10; other: 30, 100, 10;';
