Custom Path for Delta Table's Files Created from External Table underlying Files

Chandana_V — Wed, 13 Nov 2024 04:41:33 GMT

Hi,

I created a Delta table using the underlying files of an external table. I want to specify a different path for the underlying files so they aren't stored in the same location as the external table's underlying files. Is there a way to set a new path for the Delta table while keeping the external table files separate?

Thank You

Hi @Chandana_V,

For the default lakehouse table level, it not allow you to create sub folders. I'd like to suggest you store these on the file level or change to use the lakehouse which enable the preview schema features.

You can specify a different path for the underlying files of a Delta table
This way, the Delta table’s files will be separate from the external table’s files.
CREATE TABLE delta_table
USING DELTA
LOCATION 'path/to/new/delta/table';
