# Amazon CodeWhisperer integration with EMR Studio Workspaces
<a name="emr-studio-codewhisperer"></a>

## Overview
<a name="emr-studio-codewhisperer-overview"></a>

You can use [Amazon CodeWhisperer](https://docs.aws.amazon.com/codewhisperer/latest/userguide/what-is-cwspr.html) with Amazon EMR Studio to get real-time recommendations as you write code in JupyterLab. CodeWhisperer can complete your comments, finish single lines of code, make line-by-line recommendations, and generate fully-formed functions. 

**Note**  
When you use Amazon EMR Studio, AWS might store data about your usage and content for service improvement purposes. For more information and instructions to opt out of data sharing, see [Sharing your data with AWS](https://docs.aws.amazon.com/codewhisperer/latest/userguide/sharing-data.html) in the *Amazon CodeWhisperer User Guide*. 

## Considerations for using CodeWhisperer with Workspaces
<a name="emr-studio-codewhisperer-considerations"></a>
+ CodeWhisperer integration is available in the same AWS Regions where EMR Studio is available, as documented in the [EMR Studio considerations](emr-studio-considerations.md).
+ Amazon EMR Studio automatically uses the CodeWhisperer endpoint in US East (N. Virginia) (us-east-1) for recommendations, regardless of the Region that your studio is in.
+ CodeWhisperer supports only Python language for coding ETL scripts for Spark jobs in EMR Studio. 
+ A client-side telemetry option quantifies your usage of CodeWhisperer. This functionality isn't supported with EMR Studio.
