Hi,

That's usually Delta rewriting files on every UPDATE, not the row count itself. Time travel retention only affects Tables, not /Files. If your procs write staging/temp files there, Fabric won't auto-clean that, you'll need manual cleanup logic in your ETL job to delete old files yourself.

If this helped, feel free to give it a kudos or mark it as solution, helps others find it too.
