Now one way to achieve this is by using scan operation. If you are interested in using the total number of items in a table in your application's logic, that means you are going to query for the total counts pretty frequently. The only issue is that the count isn't up to date. The simplest solution is the DescribeTable which returns ItemCount. If you need pin-point accuracy, use a conditional update instead. So if a write fails or you write more than once this will be reflected in the count. The only problem this is that increment operations are not idempotent. Update operations to increment/decrement the total item count for a Possibly named "TotalNumberOfItemsPerTable" updated by making atomic Item will have Table name as it's hash key and total number of items Number of item counts for such tables in a separate table, where each The second option is what was mention by Atharva:Ī better solution that comes to my mind is to maintain the total
