putProvisionedConcurrencyConfig method

Future<PutProvisionedConcurrencyConfigResponse> putProvisionedConcurrencyConfig({ required String functionName, required int provisionedConcurrentExecutions, required String qualifier, })

Adds a provisioned concurrency configuration to a function's alias or version.

May throw InvalidParameterValueException. May throw ResourceNotFoundException. May throw ResourceConflictException. May throw TooManyRequestsException. May throw ServiceException.

Parameter functionName : The name of the Lambda function.

Name formats

• Function name - my-function.
• Function ARN - arn:aws:lambda:us-west-2:123456789012:function:my-function.
• Partial ARN - 123456789012:function:my-function.

The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

Parameter provisionedConcurrentExecutions : The amount of provisioned concurrency to allocate for the version or alias.

Parameter qualifier : The version number or alias name.
