Alibaba Cloud Data Lake DLF

Category: service

Data Lake Formation

Use Alibaba Cloud OpenAPI (RPC) with official SDKs or OpenAPI Explorer to manage resources for Data Lake Formation.

Workflow

1. Confirm region, resource identifiers, and desired action.
2. Discover API list and required parameters (see references).
3. Call API with SDK or OpenAPI Explorer.
4. Verify results with describe/list APIs.

AccessKey priority (must follow)

1. Environment variables: ALICLOUD_ACCESS_KEY_ID / ALICLOUD_ACCESS_KEY_SECRET / ALICLOUD_REGION_ID Region policy: ALICLOUD_REGION_ID is an optional default. If unset, decide the most reasonable region for the task; if unclear, ask the user.
2. Shared config file: ~/.alibabacloud/credentials

API discovery

• Product code: DataLake
• Default API version: 2020-07-10
• Use OpenAPI metadata endpoints to list APIs and get schemas (see references).

High-frequency operation patterns

1. Inventory/list: prefer List* / Describe* APIs to get current resources.
2. Change/configure: prefer Create* / Update* / Modify* / Set* APIs for mutations.
3. Status/troubleshoot: prefer Get* / Query* / Describe*Status APIs for diagnosis.

Minimal executable quickstart

Use metadata-first discovery before calling business APIs:

python scripts/list_openapi_meta_apis.py

Optional overrides:

python scripts/list_openapi_meta_apis.py --product-code  --version 

The script writes API inventory artifacts under the skill output directory.

Output policy

If you need to save responses or generated artifacts, write them under: output/aliyun-dlf-manage/

Validation

mkdir -p output/aliyun-dlf-manage
for f in skills/data-lake/aliyun-dlf-manage/scripts/*.py; do
  python3 -m py_compile "$f"
done
echo "py_compile_ok" > output/aliyun-dlf-manage/validate.txt

Pass criteria: command exits 0 and output/aliyun-dlf-manage/validate.txt is generated.

Output And Evidence

• Save artifacts, command outputs, and API response summaries under output/aliyun-dlf-manage/.
• Include key parameters (region/resource id/time range) in evidence files for reproducibility.

Prerequisites

• Configure least-privilege Alibaba Cloud credentials before execution.
• Prefer environment variables: ALICLOUD_ACCESS_KEY_ID, ALICLOUD_ACCESS_KEY_SECRET, optional ALICLOUD_REGION_ID.
• If region is unclear, ask the user before running mutating operations.
