Properties for DynamoDeleteItem 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 ‘$’)

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

  • key (Mapping[str, DynamoAttributeValue]) – Primary key of the item to retrieve. For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.

  • table (ITable) – The name of the table containing the requested item.

  • condition_expression (Optional[str]) – A condition that must be satisfied in order for a conditional DeleteItem 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]) – Determines whether item collection metrics are returned. If set to SIZE, the response includes statistics about item collections, if any, that were modified during the operation are returned in the response. If set to NONE (the default), no statistics are returned. Default: DynamoItemCollectionMetrics.NONE

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