`PATCH /api/data-classification/v1/{name=catalogs/*/config}`

Update the Data Classification configuration for a catalog.
 - The config must already exist for the catalog.
 - Updates fields specified in the update_mask.  Use update_mask field to perform partial updates of the configuration.

API scopes: dataclassification

  Field mask specifying which fields to update.

## Request body

The configuration to apply to the catalog.
 The name field in catalog_config identifies which resource to update.
- `included_schemas` (object, optional)
  Schemas to include in the scan, each named relative to the parent catalog.
   If specified, only listed schemas will be scanned.
   Mutually exclusive with `excluded_schemas`: only one may be set per request. 
   If neither `included_schemas` nor `excluded_schemas` is set, all schemas are scanned.

    Schema names, each relative to the parent catalog. Must not be empty.
- `excluded_schemas` (object, optional)
