If I create Parquet files via a Python script, how would I access that file via Dremio? Is it possible to add reflections on that file via the Reflections API?
You can add those Parquet files to a filesystem source, like HDFS, S3, NAS or a local filesystem. Once you’ve added them, you can “promote” the files to a physical dataset (PDS) in Dremio and build reflections on them.
