For help getting started with CloudFormation, see the [AWS CloudFormation User Guide](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/Welcome.html). # AWS::EntityResolution::IdMappingWorkflow Creates an `IdMappingWorkflow` object which stores the configuration of the data processing job to be run. Each `IdMappingWorkflow` must have a unique workflow name. To modify an existing workflow, use the UpdateIdMappingWorkflow API. **Important** Incremental processing is not supported for ID mapping workflows. ## Syntax To declare this entity in your CloudFormation template, use the following syntax: ### JSON ``` { "Type" : "AWS::EntityResolution::IdMappingWorkflow", "Properties" : { "[Description](#cfn-entityresolution-idmappingworkflow-description)" : String, "[IdMappingIncrementalRunConfig](#cfn-entityresolution-idmappingworkflow-idmappingincrementalrunconfig)" : IdMappingIncrementalRunConfig, "[IdMappingTechniques](#cfn-entityresolution-idmappingworkflow-idmappingtechniques)" : IdMappingTechniques, "[InputSourceConfig](#cfn-entityresolution-idmappingworkflow-inputsourceconfig)" : [ IdMappingWorkflowInputSource, ... ], "[OutputSourceConfig](#cfn-entityresolution-idmappingworkflow-outputsourceconfig)" : [ IdMappingWorkflowOutputSource, ... ], "[RoleArn](#cfn-entityresolution-idmappingworkflow-rolearn)" : String, "[Tags](#cfn-entityresolution-idmappingworkflow-tags)" : [ Tag, ... ], "[WorkflowName](#cfn-entityresolution-idmappingworkflow-workflowname)" : String } } ``` ### YAML ``` Type: AWS::EntityResolution::IdMappingWorkflow Properties: [Description](#cfn-entityresolution-idmappingworkflow-description): String [IdMappingIncrementalRunConfig](#cfn-entityresolution-idmappingworkflow-idmappingincrementalrunconfig): IdMappingIncrementalRunConfig [IdMappingTechniques](#cfn-entityresolution-idmappingworkflow-idmappingtechniques): IdMappingTechniques [InputSourceConfig](#cfn-entityresolution-idmappingworkflow-inputsourceconfig): - IdMappingWorkflowInputSource [OutputSourceConfig](#cfn-entityresolution-idmappingworkflow-outputsourceconfig): - IdMappingWorkflowOutputSource [RoleArn](#cfn-entityresolution-idmappingworkflow-rolearn): String [Tags](#cfn-entityresolution-idmappingworkflow-tags): - Tag [WorkflowName](#cfn-entityresolution-idmappingworkflow-workflowname): String ``` ## Properties `Description` A description of the workflow. *Required*: No *Type*: String *Minimum*: `0` *Maximum*: `255` *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `IdMappingIncrementalRunConfig` Property description not available. *Required*: No *Type*: [IdMappingIncrementalRunConfig](aws-properties-entityresolution-idmappingworkflow-idmappingincrementalrunconfig.md) *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `IdMappingTechniques` An object which defines the ID mapping technique and any additional configurations. *Required*: Yes *Type*: [IdMappingTechniques](aws-properties-entityresolution-idmappingworkflow-idmappingtechniques.md) *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `InputSourceConfig` A list of `InputSource` objects, which have the fields `InputSourceARN` and `SchemaName`. *Required*: Yes *Type*: Array of [IdMappingWorkflowInputSource](aws-properties-entityresolution-idmappingworkflow-idmappingworkflowinputsource.md) *Minimum*: `1` *Maximum*: `20` *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `OutputSourceConfig` A list of `IdMappingWorkflowOutputSource` objects, each of which contains fields `outputS3Path` and `KMSArn`. *Required*: No *Type*: Array of [IdMappingWorkflowOutputSource](aws-properties-entityresolution-idmappingworkflow-idmappingworkflowoutputsource.md) *Minimum*: `1` *Maximum*: `1` *Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt) `RoleArn` The Amazon Resource Name (ARN) of the IAM role.
