+# huaweicloud_dws_schema_space_managements
+
+Use this data source to get the list of schema space management information of the DWS Cluster within HuaweiCloud.
+
+## Example Usage
+
+```hcl
+variable "dws_cluster_id" {}
+variable "database_name" {}
+
+data "huaweicloud_dws_schema_space_managements" "test" {
+  cluster_id    = var.dws_cluster_id
+  database_name = var.database_name
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String) Specifies the region in which to query the resource.
+  If omitted, the provider-level region will be used.
+
+* `cluster_id` - (Required, String) Specifies the DWS cluster ID.
+
+* `database_name` - (Required, String) Specifies the database name to which the schema space management belongs.
+
+* `schema_name` - (Optional, String) Specifies the name of the schema. Fuzzy search is supported.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `schemas` - All schemas that match the filter parameters.
+
+  The [schemas](#schemas_struct) structure is documented below.
+
+<a name="schemas_struct"></a>
+The `schemas` block supports:
+
+* `database_name` - The database name corresponding to the schema.
+
+* `schema_name` - The name of the schema.
+
+* `used` - The number of schema spaces used, in bytes.
+
+* `space_limit` - The number of available spaces, in bytes.
+
+* `skew_percent` - The skew rate of the schema.
+
+* `min_value` - The number of used spaces by the DN with the minimum usage, in bytes.
+
+* `max_value` - The number of used spaces by the DN with the maximum usage, in bytes.
+
+* `dn_num` - The number of DNs.
+
+* `min_dn` - The DN that uses the least space.
+
+* `max_dn` - The DN that uses the most space.

+# huaweicloud_dws_schema_space_management
+
+Use this resource to modify schema space limit under specified DWS cluster within HuaweiCloud.
+
+-> 1. This resource is supported only in `8.1.1` or later.
+   <br>2. The space quota limit only common users but not database administrators.
+   <br>3.This resource is only a one-time action resource for modifying schema space limit. Deleting this resource will
+   not clear the corresponding request record, but will only remove the resource information from the tfstate file.
+
+## Example Usage
+
+```hcl
+variable "dws_cluster_id" {}
+variable "database_name" {}
+variable "schema_name" {}
+
+resource "huaweicloud_dws_schema_space_management" "test" {
+  cluster_id    = var.dws_cluster_id
+  database_name = var.database_name
+  schema_name   = var.schema_name
+  space_limit   = "1024"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String, ForceNew) Specifies the region in which to create the resource.
+  If omitted, the provider-level region will be used.
+  Changing this creates a new resource.
+
+* `cluster_id` - (Required, String, ForceNew) Specifies the DWS cluster ID.
+  Changing this creates a new resource.
+
+* `database_name` - (Required, String, ForceNew) Specifies the database name to which the schema space management belongs.
+  Changing this creates a new resource.
+
+* `schema_name` - (Required, String, ForceNew) Specifies the name of the schema.
+  Changing this creates a new resource.
+
+* `space_limit` - (Required, String, ForceNew) Specifies space limit of the schema, in KB.  
+  The valid value ranges from `-1` to `9,007,199,254,740,992`, `-1` and `0` means unlimited.
+
+  Changing this creates a new resource.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The resource ID.
