Constructors
DynamoUpdateItemJsonataProps()
public DynamoUpdateItemJsonataProps()Properties
Assign
Workflow variables to store in this step.
public IDictionary<string, object> Assign { get; set; }Property Value
System.
Remarks
Using workflow variables, you can store data in a step and retrieve that data in future steps.
Default: - Not assign variables
See: https://docs.aws.amazon.com/step-functions/latest/dg/workflow-variables.html
Comment
A comment describing this state.
public string Comment { get; set; }Property Value
System.
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.
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.
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.
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
IntegrationPattern
AWS Step Functions integrates with services directly in the Amazon States Language.
public Nullable<IntegrationPattern> IntegrationPattern { get; set; }Property Value
System.
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.
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.
Outputs
Used to specify and transform output from the state.
public object Outputs { get; set; }Property Value
System.
Remarks
When specified, the value overrides the state output default. The output field accepts any JSON value (object, array, string, number, boolean, null). Any string value, including those inside objects or arrays, will be evaluated as JSONata if surrounded by {% %} characters. Output also accepts a JSONata expression directly.
Default: - $states.result or $states.errorOutput
See: https://docs.aws.amazon.com/step-functions/latest/dg/concepts-input-output-filtering.html
QueryLanguage
The name of the query language used by the state.
public Nullable<QueryLanguage> QueryLanguage { get; set; }Property Value
System.
Remarks
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
ReturnConsumedCapacity
Determines the level of detail about provisioned throughput consumption that is returned in the response.
public Nullable<DynamoConsumedCapacity> ReturnConsumedCapacity { get; set; }Property Value
System.
Remarks
Default: DynamoConsumedCapacity.NONE
ReturnItemCollectionMetrics
Determines whether item collection metrics are returned.
public Nullable<DynamoItemCollectionMetrics> ReturnItemCollectionMetrics { get; set; }Property Value
System.
Remarks
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
ReturnValues
Use ReturnValues if you want to get the item attributes as they appeared before they were deleted.
public Nullable<DynamoReturnValues> ReturnValues { get; set; }Property Value
System.
Remarks
Default: DynamoReturnValues.NONE
StateName
Optional name for this state.
public string StateName { get; set; }Property Value
