scan_pdm_and_generate_logical_model(data_source_id: str, generate_ldm_request: Optional[CatalogGenerateLdmRequest] = None, scan_request: CatalogScanModelRequest = CatalogScanModelRequest(), report_warnings: bool = False) -> tuple[CatalogDeclarativeModel, CatalogScanResultPdm]
Scan data source and use returned PDM to generate logical data model. If generate_ldm_request contains PDM already, PDM tables received from the scan are appended without deduplication.
Parameters
| name | type | description |
|---|---|---|
| data_source_id | string | Data Source identification string. e.g. "demo" |
| generate_ldm_request | Optional[CatalogGenerateLdmRequest] | LDM options. Defaults to CatalogGenerateLdmRequest(separator="__", wdf_prefix="wdf") |
| scan_request | Optional[CatalogScanModelRequest] | Options for the Scan Request. Defaults to CatalogScanModelRequest(). |
| report_warnings | bool | Switch to turn on warnings. Defaults to False. |
Returns
| type | description |
|---|---|
| CatalogDeclarativeModel | Object Containing declarative Logical Data Model. |
| CatalogScanResultPdm | An instance of CatalogScanResultPdm. Containing pdm itself and a list of warnings that occurred during scanning. |
