At the time of publishing of this post, the AWS CDK has two versions of the AWS Glue module: @aws-cdk/aws-glue and @aws-cdk/aws-glue-alpha, containing L1 constructs and L2 constructs, respectively. For construct libraries, establish the lowest version of When migrating your CDK application from v1 to v2, you might want to identify the version number. Instead, write the stack's constructor to accept an optional Boolean parameter. deployment to deploy the application and create the resources. npm remove -g aws-cdk.)
