Operations
Certain cache APIs can perform multiple operations in a single request. Multi-element operations are more efficient, so the cost of these APIs is discounted at a 2:1 ratio. This means every two elements will count as one operation towards the limiter.
As an example, a SetAddElements request adding one or two elements costs one operation, but with three or four elements it costs two operations, and so on. All the APIs listed below perform multiple operations and are subject to reduced cost. All unlisted APIs cost one operation.
