Is it true that when you create a DynamoDB table, you must specify your desired throughput capacity for reads and writes?

When creating a DynamoDB table, specifying the desired throughput capacity for reads and writes is indeed a requirement, especially if you are using the provisioned capacity mode. In this mode, you must explicitly define the number of read and write capacity units the table will utilize. This allows for consistent performance based on your application's needs and lets DynamoDB allocate resources accordingly.

However, it's important to note that DynamoDB also offers an on-demand capacity mode, wherein you do not need to specify throughput capacity. This mode automatically scales up or down based on the actual consumption of read and write operations, making it more flexible for unpredictable workloads.

In summary, the requirement to specify throughput capacity depends on the capacity mode you choose. However, if you select the provisioned mode, defining this throughput is mandatory.
