Connecting Athena DB to a Glue catalog

[steven...@gmail.com]

This question has also been asked on StackOverflow, but there's not been much response. Additionally, I only recently discovered this Google Group so I thought I'd ask it here.

To replicate the SO question:

I'm confused as to how I should use Terraform to connect Athena to my Glue Catalog database.

I use 

    resource "aws_glue_catalog_database" "catalog_database" {
        name = "${var.glue_db_name}"
    }
   
    resource "aws_glue_crawler" "datalake_crawler" {
        database_name = "${var.glue_db_name}"
        name          = "${var.crawler_name}"
        role          = "${aws_iam_role.crawler_iam_role.name}"
        description   = "${var.crawler_description}"
        table_prefix  = "${var.table_prefix}"
        schedule      = "${var.schedule}"
   
        s3_target {
          path = "s3://${var.data_bucket_name[0]}"
      }
        s3_target {  
      path = "s3://${var.data_bucket_name[1]}"
      }
     }

to create a Glue DB and the crawler to crawl an s3 bucket (here only two), but I don't know how I link the Athena query service to the Glue DB. In the terraform documentation for Athena, there doesn't appear to be a way to connect Athena to a Glue cataglog but only to an S3 Bucket. Clearly, however, Athena can be integrated with Glue. 

How can I terraform an Athena database to use my Glue catalog as it's data source rather than an S3 bucket?
