Description

Modify the mutable properties of a Storage Vault.

Syntax

ALTER STORAGE VAULT <storage_vault_name>
PROPERTIES (<storage_vault_property>)

Required Parameters

<storage_vault_property>

When type is s3, the allowed property fields are as follows:

• s3.secret_key: sk for s3 vault
• vault_name: The name of the vault. When a vault is set as the default storage vault using the statement SET <original_vault_name> DEFAULT STORAGE VAULT, its name cannot be modified. To rename the vault, you must first unset the default storage vault by executing the UNSET DEFAULT STORAGE VAULT command, and then modify its name. Finally, if you need to set the renamed vault as the default storage vault, you can use the statement SET <new_vault_name> DEFAULT STORAGE VAULT.
• use_path_style: Whether to allow path style url, optional values are true, false. The default value is false.

When type is hdfs, the following fields are prohibited:

• path_prefix: Storage path prefix
• fs.defaultFS: hdfs name
