Bases:
TaskStateJsonPathBaseProps
Properties for invoking a Lambda function with LambdaInvoke using JsonPath.
- Parameters:
comment (
Optional
[str
]) – A comment describing this state. Default: No commentquery_language (
Optional
[QueryLanguage
]) – The name of the query language used by the state. If the state does not contain aqueryLanguage
field, then it will use the query language specified in the top-levelqueryLanguage
field. Default: - JSONPathstate_name (
Optional
[str
]) – Optional name for this state. Default: - The construct ID will be used as state namecredentials (
Union
[Credentials
,Dict
[str
,Any
],None
]) – Credentials for an IAM Role that the State Machine assumes for executing the task. This enables cross-account resource invocations. Default: - None (Task is executed using the State Machine’s execution role)heartbeat (
Optional
[Duration
]) – (deprecated) Timeout for the heartbeat. Default: - Noneheartbeat_timeout (
Optional
[Timeout
]) – Timeout for the heartbeat. [disable-awslint:duration-prop-type] is needed because all props interface in aws-stepfunctions-tasks extend this interface Default: - Noneintegration_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. Depending on the AWS Service, the Service Integration Pattern availability will vary. Default: -IntegrationPattern.REQUEST_RESPONSE
for most tasks.IntegrationPattern.RUN_JOB
for the following exceptions:BatchSubmitJob
,EmrAddStep
,EmrCreateCluster
,EmrTerminationCluster
, andEmrContainersStartJobRun
.task_timeout (
Optional
[Timeout
]) – Timeout for the task. [disable-awslint:duration-prop-type] is needed because all props interface in aws-stepfunctions-tasks extend this interface Default: - Nonetimeout (
Optional
[Duration
]) – (deprecated) Timeout for the task. Default: - Noneassign (
Optional
[Mapping
[str
,Any
]]) – Workflow variables to store in this step. Using workflow variables, you can store data in a step and retrieve that data in future steps. Default: - Not assign variablesinput_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: $output_path (
Optional
[str
]) – JSONPath expression to select part of the state to be the output to this state. May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}. Default: $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: $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: - Nonelambda_function (
IFunction
) – Lambda function to invoke.client_context (
Optional
[str
]) – Up to 3583 bytes of base64-encoded data about the invoking client to pass to the function. Default: - No contextinvocation_type (
Optional
[LambdaInvocationType
]) – Invocation type of the Lambda function. Default: InvocationType.REQUEST_RESPONSEpayload (
Optional
[TaskInput
]) – The JSON that will be supplied as input to the Lambda function. Default: - The state input (JSONata: ‘{% $states.input %}’, JSONPath: ‘$’)payload_response_only (
Optional
[bool
]) – Invoke the Lambda in a way that only returns the payload response without additional metadata. ThepayloadResponseOnly
property cannot be used ifintegrationPattern
,invocationType
,clientContext
, orqualifier
are specified. It always uses the REQUEST_RESPONSE behavior. Default: falsequalifier (
Optional
[str
]) – (deprecated) Version or alias to invoke a published version of the function. You only need to supply this if you want the version of the Lambda Function to depend on data in the state machine state. If not, you can pass the appropriate Alias or Version object directly as thelambdaFunction
argument. Default: - Version or alias inherent to thelambdaFunction
object.retry_on_service_exceptions (
Optional
[bool
]) – Whether to retry on Lambda service exceptions. This handlesLambda.ServiceException
,Lambda.AWSLambdaException
,Lambda.SdkClientException
, andLambda.ClientExecutionTimeoutException
with an interval of 2 seconds, a back-off rate of 2 and 6 maximum attempts. Default: true
