Error: dynamodb throughput error

The request exceeded available DynamoDB throughput. Read ThrottlingReasons and the resource ARN to identify whether the table or a secondary index is limiting the operation.

• ProvisionedThroughputExceeded: check configured capacity, consumption and auto-scaling delay.
• KeyRangeThroughputExceeded: investigate hot keys; more aggregate table capacity may not fix the partition bottleneck.
• AccountLimitExceeded: inspect the applied service quota and request an increase when appropriate.
• MaxOnDemandThroughputExceeded: review the maximum throughput setting on the table or GSI.

Use bounded retries with exponential backoff and jitter for transient throttling. For successful batch responses, also retry UnprocessedItems or UnprocessedKeys. Increasing retry counts alone can amplify sustained overload.

See DynamoDB throttling diagnosis and the AWS diagnosis workflow.
