| ## Optional Parameters | ||
|
|
||
| | Parameter Name | Description | | ||
| |-------------------|--------------------------------------------------------------| | ||
| | `retention_days` | Data retention period. Defines the duration for which the data is kept in storage. Data exceeding this period will be automatically deleted. | | ||
| | `redundancy_level`| Redundancy level. Defines the number of data replicas to ensure high availability and fault tolerance. For example, a value of 2 means each data block has two replicas. | | ||
| | `storage_type` | Storage type. Specifies the storage medium used, such as SSD, HDD, or hybrid storage. This affects performance and cost. | | ||
| | `cooloff_time` | Cool-off time. The time interval between when data is marked for deletion and when it is actually deleted. This helps prevent data loss due to accidental operations. | | ||
| | `location_policy` | Geographical location policy. Defines the geographical placement of data, such as cross-region replication for disaster recovery. | |

这些都是 PROPERTIE ("<key>"="<value>"[, ... ]) 中 key 的候选。所以这里这样组织
- 在必选参数中，增加
`PROPERTIE ("<key>"="<value>"[, ... ])`
- 然后这个表格跟在必选参数的表格后面，

Suggested change
| CREATE STORAGE VAULT [IF NOT EXISTS] <`vault_name`> [ <`properties`> ] | |
| CREATE STORAGE VAULT [IF NOT EXISTS] <vault_name> [ <properties> ] |
| | Parameter | Description | | ||
| |-------------------|--------------------------------------------------------------| | ||
| | `[IF NOT EXISTS]` | If the specified storage vault already exists, the creation operation will not be executed, and no error will be thrown. This prevents duplicate creation of the same storage vault. | | ||
| | `PROPERTIES` | A set of key-value pairs used to set or update specific properties of the storage vault. Each property consists of a key (<key>) and a value (<value>), separated by an equals sign (=). Multiple key-value pairs are separated by commas (,). | |
