+# opentelekomcloud_ddm_engines_v1
+
+Use this data source to get info of OpenTelekomCloud DDM engines.
+
+## Example Usage
+```hcl
+data "opentelekomcloud_ddm_engines_v1" "engine_list" {
+}
+```
+
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `region` - Indicates the region of the DDM engines.
+* `engines` - Indicates the DDM engines information. Structure is documented below.
+
+The `engines` block contains:
+
+  - `id` - Indicates the DDM engine ID.
+  - `name` - Indicates the DDM engine name.
+  - `version` - Indicates the DDM engine version.
+  - `availability_zones` - Indicates the supported availability zones. Structure is documented below
+
+The `availability_zones` block contains:
+
+  - `name` - Indicates the AZ name.
+  - `code` - Indicates the AZ code.
+  - `favored` - Indicates whether current AZ is favored.

+# opentelekomcloud_ddm_flavors_v1
+
+Use this data source to get info of OpenTelekomCloud DDM compute flavors.
+
+## Example Usage
+```hcl

+}
+
+data "opentelekomcloud_ddm_flavors_v1" "flavor_list" {

+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `engine_id` - (Required, String) Specifies the DDM engine ID.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `region` - Indicates the region of the DDM compute flavors.
+* `engine_id` -  See Argument Reference above.
+* `flavor_groups` - Indicates the DDM compute flvaor groups information. Structure is documented below.
+
+The `flavor_groups` block contains:
+
+  - `type` - Indicates the DDM compute flavor group type. The value can be x86 or ARM.
+  - `flavors` - Indicates the available compute flavors in the flavor group. Structure is documented below
+
+The `availability_zones` block contains:
+
+  - `id` - Indicates the compute flavor ID.
+  - `type_code` - Indicates the resource type code.
+  - `code` - Indicates the VM flavor types recorded in DDM.
+  - `iaas_code` - Indicates the VM flavor types recorded by the IaaS layer.
+  - `cpu` - Indicates the number of CPUs.
+  - `memory` - Indicates the memory size, in GB.
+  - `max_connections` - Indicates the maximum number of connections.
+  - `server_type` - Indicates the compute resource type.
+  - `architecture` - Indicates the coompute resource architecture type. The value can be x86 or ARM.
+  - `az_status` - Status of the AZ where node classes are available. The key is the AZ ID and the value is the AZ status. The value can be `normal`, `unsupported`, or `sellout`.
