The limit option will limit the number of results returned. The capacity consumed depends on the size of the items, and how many of them are accessed (I say accessed because if you have filters in place, more capacity may be consumed than the number of items actually returned would consume if there are items that get filtered out) to produce the results returned.If your application drives consistently high traffic to a single item, adaptive capacity might rebalance your data so that a partition contains only that single, frequently accessed item. In this case, DynamoDB can deliver throughput up to the partition maximum of 3,000 RCUs and 1,000 WCUs to that single item’s primary key.

DynamoDB measures the size of your billable data by adding the raw byte size of your data plus a per-item storage overhead that depends on the features you have enabled.
