Priority Attribute
Priority (priority) - attribute of any object in the structure of the external data source is a positive integer whose value does not exceed 10 000. The higher the priority, the more often the element will be selected from an array of competing elements (proportional to the value of Priority). If the Priority property is not specified or its value is less than 1, the system will consider its value to 1.
Example:
Suppose there are some elements in the array structure, each of which has the Priority attribute. Let it be required each time to choose one of the array elements. Then the sampling frequency of each element will be proportional to the value of its Priority attribute.
