Final answer:
The statement is false because DynamoDB capacity units are influenced by item size and read consistency, but Provisioned IOPS pertains to Amazon EBS, not DynamoDB. DynamoDB uses read/write capacity units to manage throughput, with other factors like query complexity and secondary indexes also affecting consumption.
Step-by-step explanation:
The statement in question is False. The DynamoDB capacity units consumed by an operation do depend on the item size and the read consistency (in the case of a read operation), but Provisioned IOPS is a term more commonly associated with Amazon EBS (Elastic Block Store) rather than DynamoDB. In DynamoDB, you deal with read/write capacity units to provision throughput capacity. These units are defined by the number of reads or writes per second as determined by the item size and consistency requirements.
For a read operation, a DynamoDB read capacity unit represents one strongly consistent read per second, or two eventually consistent reads per second, for an item up to 4KB in size. If the item size is larger, more capacity units will be consumed. For a write operation, a write capacity unit represents one write per second for an item up to 1KB in size. If you choose to use DynamoDB Auto Scaling, your capacity units can automatically adjust according to the workload demands.
It’s also important to note that other factors can influence the capacity units consumed by DynamoDB operations, such as the complexity of a query or scan operation, secondary indexes, and the use of other features like transactions.
