Specifies whether consistent reads should always be used when querying DynamoDB. Consistent reads provide the most up-to-date data, but consume more read capacity.

false

解説

When this property is set to true, the 本製品 performs consistent reads, ensuring the most up-to-date data is returned for queries and scans. However, consistent reads consume twice as many read capacity units as eventually consistent reads. Use this property only when accurate and immediate data consistency is critical for your use case.

Note: Consistent reads are not supported for global secondary indexes. If you scan or query using a secondary index, the property is ignored even if set to true.
