Choose the IAM role and S3 bucket locations for the ETL script, and so on. In this example, we call this security group glue-security-group. In this example, the following outbound traffic is allowed. However, for ENIs, it picks up the network parameter (VPC/subnet and security groups) information from only one of the JDBC connections out of the two that are configured for the ETL job. As the container is frozen after the response is returned till next request. The following table explains several scenarios and additional setup considerations for AWS Glue ETL jobs to work with more than one JDBC connection.
