Dynamodb size limit
Amazon DynamoDB currently limits the size of each item that you store in a table (see Limits in DynamoDB). If your application needs to store more data in an item than the DynamoDB size limit permits, you can try compressing one or more large attributes, or you can store them as an object in Amazon Simple Storage Service (Amazon S3) and store ...The Scan operation returns one or more items and item attributes by accessing every item in a table or a secondary index. To have DynamoDB return fewer items, you can provide a FilterExpression operation. If the total size of scanned items exceeds the maximum dataset size limit of 1 MB, the scan completes and results are returned to the user.

As you said, RCU and WCU measures the number of reads and writes (respectively) per second. However, for obvious reasons, doing a 10 byte read is not billed the same as a read of the entire database - one RCU is a read of up to 4KB, and larger reads are counted as multiple reads. WCU uses a smaller quantum (1KB). The details of the mapping depend on your usage pattern. One ph The result is not necessarily the same as the total size of all the items. For example, if BatchGetItem reads a 1.5 KB item and a 6.5 KB item, DynamoDB will calculate the size as 12 KB (4 KB + 8 KB), not 8 KB (1.5 KB + 6.5 KB).
