不 return 任何数据的 dynamodb GetItem 请求是否会消耗读取配置？
Does a dynamodb GetItem request that doesn't return any data consume read provisioning?
如果对 dynamoDB 的 GetItem 请求导致相应哈希 Key/Range 键没有条目，它是否仍计入允许的预配 table 读取次数？
是的，DynamoDB 确实消耗了配置的读取吞吐量。
If you perform a read operation on an item that does not exist,
DynamoDB will still consume provisioned read throughput: A strongly
consistent read request consumes one read capacity unit, while an
eventually consistent read request consumes 0.5 of a read capacity
unit.
