When users who have registered with the public cloud call APIs or use SDKs to access OBS, access keys (AK/SK) are required for identity authentication and request encryption. This mechanism ensures the confidentiality and integrity of a request, and the correctness of the identities of both parties.
Details about AK and SK are as follows:
In the following scenarios, you need to connect to DWS through a client or a JDBC/ODBC application to access OBS. Therefore, you must obtain the access keys (AK and SK) required for accessing OBS.
DWS provides the SQL on OBS feature to allow users to query data stored on OBS by using SELECT.
See OBS Query Overview.
Before creating the AK/SK pair, ensure that your public cloud account has passed the real-name authentication.
To create an AK/SK pair on a management console, perform the following steps:
If an AK/SK pair has been created on the Access Keys page, skip this step.
A user can create a maximum of two valid access keys. To create more access keys, delete the existing ones.
If you find that your AK/SK pair is abnormally used (for example, the AK/SK pair is lost or leaked) or will be no longer used, delete your AK/SK pair in the access key list or contact the administrator to reset your AK/SK pair.
When deleting an AK/SK pair, you need to enter the login password and either the email or mobile verification code.
Deleted AK/SK pairs cannot be restored.
