Dynamodb size limit

Unlike traditional RDBMS, DynamoDB does not have a notion of "maximal column size". The only limit is an item size limit, which is, as you've mentioned, 400 KB. That is a total limit, it inludes attribute name lenghts and attribute value lengths. I.e. the attribute names also counts towards the total size limit. Read more in the docs. Share

Jul 17, 2021 · What is the DynamoDB object size limit? DynamoDB only allows a maximum size of 400KB per DynamoDB item. The items stored within a DynamoDB database cannot exceed this limit.

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).
