Mirrored database error
I keep getting this error on csv uploads to start my mirror. I have tried multiple CSVs. What's worse is there are no MS support options related to database mirroring.
Turns out Parquet works fine and as documented. It gets hosed with the CSV. Maybe its formatting?
if you are trying to upload flat files, you should upload it to lakehouse, or you can create a pipeline/data flow to connect flat files to a lakehouse or warehouse. Can you provide more specific context (like where you are upload the flat files ? and what source are you trying to do mirroring ?)
