Considerations
- Whether the direct load operation falls back to the normal import mode when the direct load mode is not supported depends on the value of the
direct_load_allow_fallbackparameter, regardless of whether you manually add a hint to specify the direct load mode or set the default_load_mode parameter to specify the direct load mode globally.
Examples
Set the direct_load_allow_fallback parameter to True so that the direct load operation does not fail when the direct load mode is not supported and falls back to the normal import mode.
