Bases: TaskStateBaseProps

Properties for calling an AWS service’s API action from your state machine across regions.

Parameters:

comment (Optional[str]) – A comment describing this state. Default: No comment
query_language (Optional[QueryLanguage]) – The name of the query language used by the state. If the state does not contain a queryLanguage field, then it will use the query language specified in the top-level queryLanguage field. Default: - JSONPath
state_name (Optional[str]) – Optional name for this state. Default: - The construct ID will be used as state name
credentials (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: - None
heartbeat_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: - None
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. 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, and EmrContainersStartJobRun.
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: - None
timeout (Optional[Duration]) – (deprecated) Timeout for the task. Default: - None
assign (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 variables

step_concurrency_level (Union[int, float, None]) – Specifies the step concurrency level to allow multiple steps to run in parallel. Requires EMR release label 5.28.0 or above. Must be in range [1, 256]. Default: 1 - no step concurrency allowed
tags (Optional[Mapping[str, str]]) – A list of tags to associate with a cluster and propagate to Amazon EC2 instances. Default: - None
visible_to_all_users (Optional[bool]) – A value of true indicates that all IAM users in the AWS account can perform cluster actions if they have the proper IAM policy permissions. Default: true
