The company stores the leaderboard data in Amazon DynamoDB and retains the data for 30 days after an event is complete The company then uses a scheduled job to delete the old leaderboard data

The DynamoDB table is configured with a fixed write capacity. During the months when many events occur, the DynamoDB write API requests are throttled when the scheduled delete job runs.

A developer must create a long-term solution that deletes the old leaderboard data and optimizes write throughput

Answers
D.
Set a higher write capacity when the scheduled delete job runs
Suggested answer: A

Explanation:

DynamoDB TTL (Time-to-Live):A native feature that automatically deletes items after a specified expiration time.

Efficiency:Eliminates the need for scheduled deletion jobs, optimizing write throughput by avoiding potential throttling conflicts.

Seamless Integration:TTL works directly within DynamoDB, requiring minimal development overhead.
