ListLumaNamespaces - EventBridge - Alibaba Cloud Documentation Center

Lists all namespaces bound to a Luma Agent under a specified data catalog. Returns the complete set of bindings without pagination.

Operation description

Lists the namespaces bound to a Luma Agent under a specified data catalog. Results are returned in pages. Pass the NextToken from the previous response to retrieve the next page. An empty NextToken indicates that no more data is available. Expired bindings are skipped, so the number of entries on a single page may be less than the Limit value. Do not use an insufficient number of entries on the current page to determine whether the last page has been reached.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
