AWS Certified Data Engineer Associate DEA-C01 Practice Question

Switching the table to on-demand capacity mode removes the need to provision or scale write capacity in advance. DynamoDB automatically accommodates sudden traffic bursts and charges only for actual requests, so write throttling is eliminated without raising baseline capacity or adding buffering components. Adaptive capacity only redistributes existing throughput and does not prevent table-level throttling. Raising the auto-scaling maximum still leaves a lag before capacity increases and can be wasteful during normal traffic. Adding SQS and Lambda introduces extra services but does not solve the underlying write-capacity limit on the table.
