| # 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 schema space management 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. |
