/**
 * <p>You must provide the name of the partition key attribute and a single value for that
 *             attribute. <code>Query</code> returns all items with that partition key value.
 *             Optionally, you can provide a sort key attribute and use a comparison operator to refine
 *             the search results.</p>
 *          <p>Use the <code>KeyConditionExpression</code> parameter to provide a specific value for
 *             the partition key. The <code>Query</code> operation will return all of the items from
 *             the table or index with that partition key value. You can optionally narrow the scope of
 *             the <code>Query</code> operation by specifying a sort key value and a comparison
 *             operator in <code>KeyConditionExpression</code>. To further refine the
 *                 <code>Query</code> results, you can optionally provide a
 *                 <code>FilterExpression</code>. A <code>FilterExpression</code> determines which
 *             items within the results should be returned to you. All of the other results are
 *             discarded. </p>
 *          <p> A <code>Query</code> operation always returns a result set. If no matching items are
 *             found, the result set will be empty. Queries that do not return results consume the
 *             minimum number of read capacity units for that type of read operation. </p>
 *          <note>
 *             <p> DynamoDB calculates the number of read capacity units consumed based on item
 *                 size, not on the amount of data that is returned to an application. The number of
 *                 capacity units consumed will be the same whether you request all of the attributes
 *                 (the default behavior) or just some of them (using a projection expression). The
 *                 number will also be the same whether or not you use a <code>FilterExpression</code>.
 *             </p>
 *          </note>
 *          <p>
 *             <code>Query</code> results are always sorted by the sort key value. If the data type of
 *             the sort key is Number, the results are returned in numeric order; otherwise, the
 *             results are returned in order of UTF-8 bytes. By default, the sort order is ascending.
 *             To reverse the order, set the <code>ScanIndexForward</code> parameter to false. </p>
 *          <p> A single <code>Query</code> operation will read up to the maximum number of items set
 *             (if using the <code>Limit</code> parameter) or a maximum of 1 MB of data and then apply
 *             any filtering to the results using <code>FilterExpression</code>. If
 *                 <code>LastEvaluatedKey</code> is present in the response, you will need to paginate
 *             the result set. For more information, see <a href="https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Query.html#Query.Pagination">Paginating
 *                 the Results</a> in the <i>Amazon DynamoDB Developer Guide</i>. </p>
 *          <p>
 *             <code>FilterExpression</code> is applied after a <code>Query</code> finishes, but before
 *             the results are returned. A <code>FilterExpression</code> cannot contain partition key
 *             or sort key attributes. You need to specify those attributes in the
 *                 <code>KeyConditionExpression</code>. </p>
 *          <note>
 *             <p> A <code>Query</code> operation can return an empty result set and a
 *                     <code>LastEvaluatedKey</code> if all the items read for the page of results are
 *                 filtered out. </p>
 *          </note>
 *          <p>You can query a table, a local secondary index, or a global secondary index. For a
 *             query on a table or on a local secondary index, you can set the
 *                 <code>ConsistentRead</code> parameter to <code>true</code> and obtain a strongly
 *             consistent result. Global secondary indexes support eventually consistent reads only, so
 *             do not specify <code>ConsistentRead</code> when querying a global secondary
 *             index.</p>
