Question
A company has an application that uses an Amazon DynamoDB table to store user data. Every morning, a single-threaded process calls the DynamoDB API Scan operation to scan the entire table and generate a critical start-of-day report for management. A successful marketing campaign recently doubled the number of items in the table, and now the process takes too long to run and the report is not generated in time. A database specialist needs to improve the performance of the process. The database specialist notes that, when the process is running, 15% of the table's provisioned read capacity units (RCUs) are being used. What should the database specialist do?
Options
- AEnable auto scaling for the DynamoDB table.
- BUse four threads and parallel DynamoDB API Scan operations.
- CDouble the table's provisioned RCUs.
- DSet the Limit and Offset parameters before every call to the API.
