+# Resource: scaleway_datawarehouse_database
+
+Creates and manages Scaleway Data Warehouse databases within a deployment.
+For more information refer to the [product documentation](https://www.scaleway.com/en/docs/data-warehouse/).
+
+## Example Usage
+
+### Basic
+
+```terraform
+resource "scaleway_datawarehouse_deployment" "main" {
+  name           = "my-datawarehouse"
+  version        = "v25"
+  replica_count  = 1
+  cpu_min        = 2
+  cpu_max        = 4
+  ram_per_cpu    = 4
+  password       = "thiZ_is_v&ry_s3cret"
+}
+
+resource "scaleway_datawarehouse_database" "main" {
+  deployment_id = scaleway_datawarehouse_deployment.main.id
+  name          = "my_database"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+- `deployment_id` - (Required) ID of the Data Warehouse deployment to which this database belongs.
+- `name` - (Required) Name of the database.
+- `region` - (Defaults to [provider](../index.md#region) `region`) The [region](../guides/regions_and_zones.md#regions) in which the database should be created.
+
+## Attributes Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+- `id` - The ID of the database (format: `{region}/{deployment_id}/{name}`).
+- `size` - Size of the database in GB.
+
+## Import
+
+Data Warehouse databases can be imported using the `{region}/{deployment_id}/{name}`, e.g.
+
+```bash
+terraform import scaleway_datawarehouse_database.main fr-par/11111111-1111-1111-1111-111111111111/my_database
+```

+
+### Basic
+

+resource "scaleway_datawarehouse_deployment" "main" {
+  name           = "my-datawarehouse"
+  version        = "v25"
+  replica_count  = 1

+  cpu_max        = 4
+  ram_per_cpu    = 4
+  password       = "thiZ_is_v&ry_s3cret"
+}
+```
+
+### With Tags
+
+```terraform
+resource "scaleway_datawarehouse_deployment" "main" {
+  name           = "my-datawarehouse"
+  version        = "v25"
+  replica_count  = 1
+  cpu_min        = 2
+  cpu_max        = 4
+  ram_per_cpu    = 4
+  password       = "thiZ_is_v&ry_s3cret"
+  tags           = ["production", "analytics"]
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+- `name` - (Required) Name of the Data Warehouse deployment.
+- `version` - (Required, Forces new resource) ClickHouse version to use (e.g., "v25"). Changing this forces recreation of the deployment.
+- `replica_count` - (Required) Number of replicas.
+- `cpu_min` - (Required) Minimum CPU count. Must be less than or equal to `cpu_max`.
+- `cpu_max` - (Required) Maximum CPU count. Must be greater than or equal to `cpu_min`.
+- `ram_per_cpu` - (Required) RAM per CPU in GB.
+- `password` - (Optional) Password for the first user of the deployment. If not specified, a random password will be generated. Note: password is only used during deployment creation.
+- `tags` - (Optional) List of tags to apply to the deployment.
+- `region` - (Defaults to [provider](../index.md#region) `region`) The [region](../guides/regions_and_zones.md#regions) in which the deployment should be created.
+- `project_id` - (Defaults to [provider](../index.md#project_id) `project_id`) The ID of the project the deployment is associated with.
+
+~> **Important:** Private endpoints are not yet supported by the API. A public endpoint is always created automatically.
+
+~> **Note:** During the private beta phase, modifying `cpu_min`, `cpu_max`, and `replica_count` has no effect until the feature is launched in general availability.
+
+## Attributes Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+- `id` - The ID of the deployment.
+- `status` - The status of the deployment (e.g., "ready", "provisioning").
+- `created_at` - Date and time of deployment creation (RFC 3339 format).
+- `updated_at` - Date and time of deployment last update (RFC 3339 format).
+- `public_network` - Public endpoint information (always created automatically).
+    - `id` - The ID of the public endpoint.
+    - `dns_record` - DNS record for the public endpoint.
+    - `services` - List of services exposed on the public endpoint.
+        - `protocol` - Service protocol (e.g., "tcp", "https", "mysql").
+        - `port` - TCP port number.
+
+## Import
+
+Data Warehouse deployments can be imported using the `{region}/{id}`, e.g.
+
+```bash
+terraform import scaleway_datawarehouse_deployment.main fr-par/11111111-1111-1111-1111-111111111111
