Dremio, minio, sql server

Hi, i tried to setup minio as data lake, and imported data from my sql server into minio using method from here How to Build a Modern Data Lake with MinIO | by Tejas Marvadi | CodeX | Medium.

I managed to connect to minio in dremio using method suggested from here Amazon S3 - Dremio
but i cannot query the data.

Failed at the step to setup dataset. “format unknown”.

May i know how to solve this problem? Or minio is not the data lake to use?

@tk.l Your error seems to say “format nknown”, what is the format of the files? Is it JSON or PARQUET etc?
