When using a large Scan operation in DynamoDB, what technique can be used to minimize the impact of a scan on a
table’s provisioned throughput?
A.
Set a smaller page size for the scan
B.
Use parallel scans
C.
Define a range index on the table
D.
Prewarm the table by updating all items
Actual answer is A – it will return less items per round, reducing throughput impact.
Parallel scans will maximize impact, range index has no effect on scan operation, prewarm is nonsense.
