Tonic Structural uses Amazon Athena to run queries against your AWS Glue catalog. These queries are typically for powering the front-end experience. They are also used in conjunction with gathering data used by certain generators during a data generation.
To use Athena, you must set up the required permissions, and also create an Athena Workgroup. You can do this from the Athena homepage in the AWS Console.
By default, Structural expects the WorkGroup name to be tonic-emr-workgroup. To override the default value, configure the following environment setting:
If you do override this value, you must override it in both the Structural web server container and on the Amazon EMR cluster.
