A builder for QueryOutput
Implementations
Appends an item to items
.
To override the contents of this collection use set_items
.
An array of item attributes that match the query criteria. Each element in this array consists of an attribute name and the value for that attribute.

The number of items in the response.
If you used a QueryFilter
in the request, then Count
is the
number of items returned after the filter was applied, and ScannedCount
is
the number of matching items before the filter was applied.
If you did not use a filter in the request, then Count
and
ScannedCount
are the same.

The number of items evaluated, before any QueryFilter
is applied. A high
ScannedCount
value with few, or no, Count
results
indicates an inefficient Query
operation. For more information, see Count and
ScannedCount in the Amazon DynamoDB Developer
Guide.

is the same

Adds a key-value pair to last_evaluated_key
.
To override the contents of this collection use set_last_evaluated_key
.
The primary key of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request.
If LastEvaluatedKey
is empty, then the "last page" of results has been
processed and there is no more data to be retrieved.
If LastEvaluatedKey
is not empty, it does not necessarily mean that there
is more data in the result set. The only way to know when you have reached the end of
the result set is when LastEvaluatedKey
is empty.

The capacity units consumed by the Query
operation. The data returned
includes the total provisioned throughput consumed, along with statistics for the table
and any indexes involved in the operation. ConsumedCapacity
is only
returned if the ReturnConsumedCapacity
parameter was specified. For more
information, see Provisioned Throughput in the Amazon DynamoDB Developer
Guide.
