Submit a bulk update of per-object parameters via CSV or JSON. The request is processed asynchronously. Use the returned job_id to poll the job status endpoint.

Field applicability by object type:
| Field | Schema | Table | Attribute | |-------|--------|-------|-----------| | excluded | Yes | Yes | No | | sensitive | Yes | Yes | Yes | | skip_profiling | Yes | Yes | No | | skip_view_profiling | Yes | No | No | | num_rows_to_profile | Yes | Yes | No | | num_sample_rows | Yes | Yes | No | | num_profile_values | No | No | Yes | | custom_profiling_query | No | Yes | Yes |

Cascade behavior:

• excluded: schema cascades to tables + attributes; table cascades to attributes.
• sensitive: schema cascades to tables + attributes; table cascades to attributes.
• skip_profiling: schema cascades to tables.

Key format:

• Schema: <ds_id>.<schema_name>
• Table: <ds_id>.<schema_name>.<table_name>
• Attribute: <ds_id>.<schema_name>.<table_name>.<attribute_name>
• Multi-schema datasources automatically add a catalog component.
