# AWS::Greengrass::FunctionDefinitionVersion FunctionConfiguration
<a name="aws-properties-greengrass-functiondefinitionversion-functionconfiguration"></a>

<a name="aws-properties-greengrass-functiondefinitionversion-functionconfiguration-description"></a>The group-specific configuration settings for a Lambda function. These settings configure the function's behavior in the Greengrass group. For more information, see [Controlling Execution of Greengrass Lambda Functions by Using Group-Specific Configuration](https://docs.aws.amazon.com/greengrass/v1/developerguide/lambda-group-config.html) in the * AWS IoT Greengrass Version 1 Developer Guide *.

<a name="aws-properties-greengrass-functiondefinitionversion-functionconfiguration-inheritance"></a> In an CloudFormation template, `FunctionConfiguration` is a property of the [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-greengrass-functiondefinitionversion-function.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-greengrass-functiondefinitionversion-function.html) property type.

## Properties
<a name="aws-properties-greengrass-functiondefinitionversion-functionconfiguration-properties"></a>

`EncodingType`  <a name="cfn-greengrass-functiondefinitionversion-functionconfiguration-encodingtype"></a>
The expected encoding type of the input payload for the function. Valid values are `json` (default) and `binary`.  
*Required*: No  
*Type*: String  
*Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)

`Environment`  <a name="cfn-greengrass-functiondefinitionversion-functionconfiguration-environment"></a>
The environment configuration of the function.  
*Required*: No  
*Type*: [Environment](aws-properties-greengrass-functiondefinitionversion-environment.md)  
*Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)

`ExecArgs`  <a name="cfn-greengrass-functiondefinitionversion-functionconfiguration-execargs"></a>
The execution arguments.  
*Required*: No  
*Type*: String  
*Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)

`Executable`  <a name="cfn-greengrass-functiondefinitionversion-functionconfiguration-executable"></a>
The name of the function executable.  
*Required*: No  
*Type*: String  
*Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)

`MemorySize`  <a name="cfn-greengrass-functiondefinitionversion-functionconfiguration-memorysize"></a>
The memory size (in KB) required by the function.  
This property applies only to Lambda functions that run in a Greengrass container.
*Required*: No  
*Type*: Integer  
*Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)

`Pinned`  <a name="cfn-greengrass-functiondefinitionversion-functionconfiguration-pinned"></a>
Indicates whether the function is pinned (or *long-lived*). Pinned functions start when the core starts and process all requests in the same container. The default value is false.  
*Required*: No  
*Type*: Boolean  
*Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)
