A builder for ScanOutput
Implementations
Appends an item to items
.
To override the contents of this collection use set_items
.
An array of item attributes that match the scan 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 set ScanFilter
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
is the same as ScannedCount
.

If you did not use a filter in the request, then Count

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

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 Scan
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.
