Write data into a shortcut to ADLSg2

Is it possible to write data into a table stored in ADLSg2 referenced by shortcut? Or is it just for read-only operations?

    Hi amaaiia you are able to write to Delta tables stored in ADLSGen2 using a shortcut in a Fabric Lakehouse.  In the attached image, I have a shortcut to an ADLSGen2 account with a Delta table.  I can then read and write data to it.

     

     

    You can also write Files too.

Hi amaaiia 

No, shortcuts in Microsoft Fabric for ADLS Gen2 are for read-only operations. You cannot directly write data into a table referenced by a shortcut.

Here's why:

  • Shortcuts are pointers to existing data locations. They don't create copies of the data.
  • Fabric uses the shortcut to access the original data in ADLS Gen2.

Hope this helps. Please let me know if you have any further questions.

Anonymous shortcuts are not read only.  Shortcuts also enable you to write back to the shortcut location.  S3 and Google are not supported for write operations via Shortcuts, but ADLSGen2 is supported for write operations.
