Curios question: why not let the code do this themselves? Like create the real table with a temp name and the name which corresponds to the filename as a view with this simple select star?

@jankatins Good catch actually - Thanks! Haven't considered such an option to be honest. Will think on it - since it might eliminate several downsides of the solution

What about the following approach:

  • Create a CTAS with random name (and specific location) (1)
  • Create the target table as a CTA with the NO DATA, so it only copy the table structure.
  • Use Glue API to point the target table location to the S3 files from (1)
  • Drop the Athena table created from (1)
