Each partition on a DynamoDB table is subject to a hard limit of 1,000 write capacity units and 3,000 read capacity units. A table is a collection of items, and each item is a collection of attributes. In a nutshell, Aurora throughput is super cost effective. Each of these calls is billed on RRU basis and returns up to 1MB of data. The default value for the pricing model is Cost optimized. Moreover, if you have any many-to-many relationships, remember that you need to take care of "orphaned records" on your own. While the query is using partition and sort key to get the desired piece of data fast and directly, the scan, on the other hand, is "scanning" through your whole table. At MongoDB, we think that data visualization is a critical part of any data platform. Continuous backup automation for Amazon DynamoDB. Use our interactive API cost calculator to learn more.
