With the recent update each consumed capacity data point now represents the average units consumed per second (take the previous number and divide by 300). Because DynamoDB in both On-Demand and Provisioned capacity mode uses size-dependent billing units (1 WCU/WRU = 1KB, 1 RCU/RRU = 4KB), plus, you're paying for storage too, you should always aim to make your records as small as possible. improved ratio of consumed to provisioned capacity, which reduces the wasted overhead while providing sufficient operating capacity.
