When mirroring from Azure SQL to Fabric all Varchar columns are created on the mirrored database as VARCHAR(8000) instead of preserving their original sizes. Is this by design?
Solved! Go to Solution.
It's a current documented limitation. The hope is that this will be lifted.
I do see documentation of the limit of size for VARCHAR fields being 8000 and VARCHAR(MAX) is in public preview for warehouses but I can't find documentation that states that ALL FIELDS will be converted to VARCHAR(8000) during mirroring. Can you please point me to that doc?
