In OceanBase Database V4.x, the corresponding logic is changed, and the corresponding feature is no longer available. This parameter has been deprecated since OceanBase Database V4.2.0.

Attributes

Attribute Description
Type String
Default value other: 100,100,100
Effective upon OBServer node restart No

Considerations

The percentages of each type of I/O requests of a tenant are specified in the following format: category_name: min_percent, max_percent, weight_percent. Settings for multiple types are separated by semicolons (;). Unspecified types are represented by other.

The sum of the min_percent fields of all types, and that of the weight_percent fields of all types, including the other type, are 100.

Examples

Configure the percentages of each type of I/O requests for a tenant.
