v0.4.0

Modify type of glue-catalog-table partition_keys variable @joe-niland (#8)

what

• Modify glue-catalog-table partition_keys variable to allow specification of multiple partition keys
• Add example var value to fixtures to include testing of this var

why

• Existing code appeared to support a single partition key, e.g.

    partition_keys = {
      name    = "test"
      comment = "test"
      type    = "string"
    }
