Properties
Comment
An optional description for this state.
public string Comment { get; set; }
Property Value
System.String
Remarks
Default: - No comment
ConditionExpression
A condition that must be satisfied in order for a conditional DeleteItem to succeed.
public string ConditionExpression { get; set; }
Property Value
System.String
Remarks
Default: - No condition expression
Credentials
Credentials for an IAM Role that the State Machine assumes for executing the task.
public ICredentials Credentials { get; set; }
Property Value
Remarks
This enables cross-account resource invocations.
Default: - None (Task is executed using the State Machine's execution role)
See: https://docs.aws.amazon.com/step-functions/latest/dg/concepts-access-cross-acct-resources.html
ExpressionAttributeNames
One or more substitution tokens for attribute names in an expression.
public IDictionary<string, string> ExpressionAttributeNames { get; set; }
Property Value
System.Collections.Generic.IDictionary<System.String, System.String>
Remarks
Default: - No expression attribute names
ExpressionAttributeValues
One or more values that can be substituted in an expression.
public IDictionary<string, DynamoAttributeValue> ExpressionAttributeValues { get; set; }
Property Value
System.Collections.Generic.IDictionary<System.String, DynamoAttributeValue>
Remarks
Default: - No expression attribute values
Heartbeat
(deprecated) Timeout for the heartbeat.
public Duration Heartbeat { get; set; }
Property Value
Remarks
Default: - None
Stability: Deprecated
HeartbeatTimeout
Timeout for the heartbeat.
public Timeout HeartbeatTimeout { get; set; }
Property Value
Remarks
[disable-awslint:duration-prop-type] is needed because all props interface in aws-stepfunctions-tasks extend this interface
Default: - None
InputPath
JSONPath expression to select part of the state to be the input to this state.
public string InputPath { get; set; }
Property Value
System.String
Remarks
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 '$')
IntegrationPattern
AWS Step Functions integrates with services directly in the Amazon States Language.
public Nullable<IntegrationPattern> IntegrationPattern { get; set; }
Property Value
System.Nullable<IntegrationPattern>
Remarks
You can control these AWS services using service integration patterns.
Depending on the AWS Service, the Service Integration Pattern availability will vary.
Default: - IntegrationPattern.REQUEST_RESPONSE
for most tasks.
IntegrationPattern.RUN_JOB
for the following exceptions:
BatchSubmitJob
, EmrAddStep
, EmrCreateCluster
, EmrTerminationCluster
, and EmrContainersStartJobRun
.
See: https://docs.aws.amazon.com/step-functions/latest/dg/connect-supported-services.html
Key
Primary key of the item to retrieve.
public IDictionary<string, DynamoAttributeValue> Key { get; set; }
Property Value
System.Collections.Generic.IDictionary<System.String, DynamoAttributeValue>
Remarks
For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.
OutputPath
JSONPath expression to select select a portion of the state output to pass to the next state.
public string OutputPath { get; set; }
Property Value
System.String
Remarks
May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}.
Default: - The entire JSON node determined by the state input, the task result, and resultPath is passed to the next state (JSON path '$')
ResultPath
JSONPath expression to indicate where to inject the state's output.
public string ResultPath { get; set; }
Property Value
System.String
Remarks
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 '$')
ResultSelector
The JSON that will replace the state's raw result and become the effective result before ResultPath is applied.
public IDictionary<string, object> ResultSelector { get; set; }

System.Collections.Generic.IDictionary<System.String, System.Object>
Remarks
You can use ResultSelector to create a payload with values that are static or selected from the state's raw result.
Default: - None
