A DynamoDB query that returns an empty result set consumes any capacity?

If my query in the DynamoDB table returns an empty result set, is it calculated in reserve capacity? If this is not the case, does this mean that I can query as often as I want, without throttling, while there is no record?

You will still use read bandwidth if there is an empty result set.

Relevant section from the File Size Size Documentation :

If you are performing a read operation on an element that does not exist, DynamoDB will still consume the provided read throughput: a highly consistent read request consumes one reader module, while a consistent read request consumes 0.5 units of read capacity.
