Bases: aws_cdk.aws_stepfunctions.TaskStateBaseProps

Properties for DynamoPutItem Task.

Parameters

  • comment (Optional[str]) – An optional description for this state. Default: - No comment

  • heartbeat (Optional[Duration]) – Timeout for the heartbeat. Default: - None

  • input_path (Optional[str]) – JSONPath expression to select part of the state to be the input to this state. May also be the special value JsonPath.DISCARD, which will cause the effective input to be the empty object {}. Default: - The entire task input (JSON path ‘$’)

  • integration_pattern (Optional[IntegrationPattern]) – AWS Step Functions integrates with services directly in the Amazon States Language. You can control these AWS services using service integration patterns Default: IntegrationPattern.REQUEST_RESPONSE

  • output_path (Optional[str]) – JSONPath expression to select select a portion of the state output to pass to the next state. May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}. Default: - The entire JSON node determined by the state input, the task result, and resultPath is passed to the next state (JSON path ‘$’)

  • result_path (Optional[str]) – JSONPath expression to indicate where to inject the state’s output. May also be the special value JsonPath.DISCARD, which will cause the state’s input to become its output. Default: - Replaces the entire input with the result (JSON path ‘$’)

  • result_selector (Optional[Mapping[str, Any]]) – The JSON that will replace the state’s raw result and become the effective result before ResultPath is applied. You can use ResultSelector to create a payload with values that are static or selected from the state’s raw result. Default: - None

  • timeout (Optional[Duration]) – Timeout for the state machine. Default: - None

  • item (Mapping[str, DynamoAttributeValue]) – A map of attribute name/value pairs, one for each attribute. Only the primary key attributes are required; you can optionally provide other attribute name-value pairs for the item.

  • table (ITable) – The name of the table where the item should be written .

  • condition_expression (Optional[str]) – A condition that must be satisfied in order for a conditional PutItem operation to succeed. Default: - No condition expression

  • expression_attribute_names (Optional[Mapping[str, str]]) – One or more substitution tokens for attribute names in an expression. Default: - No expression attribute names

  • expression_attribute_values (Optional[Mapping[str, DynamoAttributeValue]]) – One or more values that can be substituted in an expression. Default: - No expression attribute values

  • return_consumed_capacity (Optional[DynamoConsumedCapacity]) – Determines the level of detail about provisioned throughput consumption that is returned in the response. Default: DynamoConsumedCapacity.NONE

  • return_item_collection_metrics (Optional[DynamoItemCollectionMetrics]) – The item collection metrics to returned in the response. Default: DynamoItemCollectionMetrics.NONE

  • return_values (Optional[DynamoReturnValues]) – Use ReturnValues if you want to get the item attributes as they appeared before they were updated with the PutItem request. Default: DynamoReturnValues.NONE
