RequestLimitExceeded

class DynamoDB.Client.exceptions.RequestLimitExceeded

Throughput exceeds the current throughput quota for your account. For detailed information about why the request was throttled and the ARN of the impacted resource, find the ThrottlingReason field in the returned exception. Contact Amazon Web Services Support to request a quota increase.

Example

try:
  ...
except client.exceptions.RequestLimitExceeded as e:
  print(e.response)

response

The parsed error response. All exceptions have a top level Error key that provides normalized access to common exception atrributes. All other keys are specific to this service or exception class.

Structure

• (dict) –

  Throughput exceeds the current throughput quota for your account. For detailed information about why the request was throttled and the ARN of the impacted resource, find the ThrottlingReason field in the returned exception. Contact Amazon Web Services Support to request a quota increase.

  • message (string) –

  • ThrottlingReasons (list) –

    A list of ThrottlingReason that provide detailed diagnostic information about why the request was throttled.

    • (dict) –

      Represents the specific reason why a DynamoDB request was throttled and the ARN of the impacted resource. This helps identify exactly what resource is being throttled, what type of operation caused it, and why the throttling occurred.

      • reason (string) –

        The reason for throttling. The throttling reason follows a specific format: ResourceType+OperationType+LimitType:

        • Resource Type (What is being throttled): Table or Index

        • Operation Type (What kind of operation): Read or Write

        • Limit Type (Why the throttling occurred):

          • ProvisionedThroughputExceeded: The request rate is exceeding the provisioned throughput capacity (read or write capacity units) configured for a table or a global secondary index (GSI) in provisioned capacity mode.

          • AccountLimitExceeded: The request rate has caused a table or global secondary index (GSI) in on-demand mode to exceed the per-table account-level service quotas for read/write throughput in the current Amazon Web Services Region.

          • KeyRangeThroughputExceeded: The request rate directed at a specific partition key value has exceeded the internal partition-level throughput limits, indicating uneven access patterns across the table’s or GSI’s key space.

          • MaxOnDemandThroughputExceeded: The request rate has exceeded the configured maximum throughput limits set for a table or index in on-demand capacity mode.

        Examples of complete throttling reasons:

        • TableReadProvisionedThroughputExceeded

        • IndexWriteAccountLimitExceeded

        This helps identify exactly what resource is being throttled, what type of operation caused it, and why the throttling occurred.

      • resource (string) –

        The Amazon Resource Name (ARN) of the DynamoDB table or index that experienced the throttling event.

  • Error (dict) – Normalized access to common exception attributes.

    • Code (string) – An identifier specifying the exception type.

    • Message (string) – A descriptive message explaining why the exception occured.
