How can I get the total number of items in a DynamoDB table?

Question

I want to know how many items are in my dynamodb table. From the API guide, one way to do it is using a scan as follows:

Answer 1

Please do not use scan method of dynamoDb because it read all data of tabel but in this case u need only count so use this .

$scan_response = $dynamodb->describeTable(array(
'TableName' => 'ProductCatalog' ));

and print this for result $scan_response['Table']['ItemCount']
