how do we version control an aws glue workflow?

Hi,

You can use a source control tool (e.g., AWS CodeCommit) for checking in and versioning your AWS Glue ETL source code and AWS Glue Workflow CloudFormation template files. Refer the following two blogs which provide more details regarding the same...

1. Using AWS DevOps Tools to model and provision AWS Glue workflows https://aws.amazon.com/blogs/devops/provision-codepipeline-glue-workflows/

2. Implement continuous integration and delivery of serverless AWS Glue ETL applications using AWS Developer Tools https://aws.amazon.com/blogs/big-data/implement-continuous-integration-and-delivery-of-serverless-aws-glue-etl-applications-using-aws-developer-tools/

Hope this helps!
