DLF Data Lake Metadata Query

Query Catalog, Database, and Table metadata resources in Alibaba Cloud Data Lake Formation (DLF).

CRITICAL: Use only the Python SDK script provided by this Skill. All operations go through the DLF Python SDK (alibabacloud-dlfnext20250310) via scripts/dlf_metadata_query.py. This Skill does not invoke any shell-based command-line client and does not require AI-Mode configuration.

• DO NOT attempt access via any shell-based command-line client — DLF is not exposed through one in this Skill
• DO NOT use curl, wget, or other HTTP clients to call the DLF API directly
• MUST use the scripts/dlf_metadata_query.py script provided by this Skill, which wraps the DLF Python SDK
• All query operations are executed via python3 scripts/dlf_metadata_query.py <action> [options]
