Quizplus · Accepted Answer

Each write capacity unit in DynamoDB can handle 1KB per second. Since each record is 1.5KB, you need 1.5 write capacity units per record. For 10 million records, you need 15 million write capacity units per hour. Dividing by 3600 seconds in an hour gives 4166.67, which rounds up to 5556 write capacity units.
