# AWS::AppFlow::Flow Task
<a name="aws-properties-appflow-flow-task"></a>

 A class for modeling different type of tasks. Task implementation varies based on the `TaskType`. 

## Syntax
<a name="aws-properties-appflow-flow-task-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-appflow-flow-task-syntax.json"></a>

```
{
  "[ConnectorOperator](#cfn-appflow-flow-task-connectoroperator)" : {{ConnectorOperator}},
  "[DestinationField](#cfn-appflow-flow-task-destinationfield)" : {{String}},
  "[SourceFields](#cfn-appflow-flow-task-sourcefields)" : {{[ String, ... ]}},
  "[TaskProperties](#cfn-appflow-flow-task-taskproperties)" : {{[ TaskPropertiesObject, ... ]}},
  "[TaskType](#cfn-appflow-flow-task-tasktype)" : {{String}}
}
```

### YAML
<a name="aws-properties-appflow-flow-task-syntax.yaml"></a>

```
  [ConnectorOperator](#cfn-appflow-flow-task-connectoroperator): {{
    ConnectorOperator}}
  [DestinationField](#cfn-appflow-flow-task-destinationfield): {{String}}
  [SourceFields](#cfn-appflow-flow-task-sourcefields): {{
    - String}}
  [TaskProperties](#cfn-appflow-flow-task-taskproperties): {{
    - TaskPropertiesObject}}
  [TaskType](#cfn-appflow-flow-task-tasktype): {{String}}
```

## Properties
<a name="aws-properties-appflow-flow-task-properties"></a>

`ConnectorOperator`  <a name="cfn-appflow-flow-task-connectoroperator"></a>
 The operation to be performed on the provided source fields.

 A field in a destination connector, or a field value against which Amazon AppFlow validates a source field.   
*Required*: No  
*Type*: String  
*Maximum*: `256`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`TaskType`  <a name="cfn-appflow-flow-task-tasktype"></a>
Specifies the particular task implementation that Amazon AppFlow performs.  
*Allowed values*: `Arithmetic` \| `Filter` \| `Map` \| `Map_all` \| `Mask` \| `Merge` \| `Truncate` \| `Validate`  
*Required*: Yes  
*Type*: String  
*Allowed values*: `Arithmetic | Filter | Map | Map_all | Mask | Merge | Passthrough | Truncate | Validate | Partition`
