DynamoDB (DDB) is the managed NoSQL database service from AWS.
As DDB pricing is based on the amount of read and write capacity units provisioned, it is important to be able to calculate the requirements for your use case.
This recipe uses a written formula to estimate the required read capacity units (RCU) and write capacity units (WCU) that should be allocated to you DDB table.
It is also crucial to remember that while new partitions will be automatically added to a DDB table, they cannot be automatically taken away. This means that excessive partitioning can cause long-term impacts to your performance, so you should be aware of them.
