+# google_bigquery_dataset
+
+Creates a dataset resource for Google BigQuery. For more information see
+[the official documentation](https://cloud.google.com/bigquery/docs/) and
+[API](https://cloud.google.com/bigquery/docs/reference/rest/v2/datasets).
+
+
+## Example Usage
+
+```hcl
+resource "google_bigquery_dataset" "default" {
+  dataset_id                  = "test"
+  friendly_name               = "test"
+  description                 = "This is a test description"
+  location                    = "EU"
+  default_table_expiration_ms = 3600000
+
+  labels {
+    env = "default"
+  }
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `dataset_id` - (Required) A unique ID for the resource.
+    Changing this forces a new resource to be created.
+
+* `project` - (Optional) The project in which the resource belongs. If it
+    is not provided, the provider project is used.
+
+* `friendly_name` - (Optional) A descriptive name for the dataset.
+
+* `description` - (Optional) A user-friendly description of the dataset.
+
+* `location` - (Optional) The geographic location where the dataset should reside.
+
+    Possible values include `EU` and `US`. The default value is `US`.
+
+    Changing this forces a new resource to be created.
+
+* `default_table_expiration_ms` - (Optional) The default lifetime of all
+    tables in the dataset, in milliseconds. The minimum value is 3600000
+    milliseconds (one hour).
+
+    Once this property is set, all newly-created
+    tables in the dataset will have an expirationTime property set to the
+    creation time plus the value in this property, and changing the value
+    will only affect new tables, not existing ones. When the
+    expirationTime for a given table is reached, that table will be
+    deleted automatically. If a table's expirationTime is modified or
+    removed before the table expires, or if you provide an explicit
+    expirationTime when creating a table, that value takes precedence
+    over the default expiration time indicated by this property.
+
+  * `labels` - (Optional) A mapping of labels to assign to the resource.
+
+## Attributes Reference
+
+In addition to the arguments listed above, the following computed attributes are
+exported:
+
+* `self_link` - The URI of the created resource.
+
+* `etag` - A hash of the resource.
+
+* `creation_time` - The time when this dataset was created, in milliseconds since the epoch.
+
+* `last_modified_time` -  The date when this dataset or any of its tables was last modified,
+  in milliseconds since the epoch.
