Thanks for mentioning the new interesting commands.

According to https://learn.microsoft.com/en-us/sql/t-sql/functions/jaro-winkler-distance-transact-sql?view=azuresqldb-current it's still in preview

I wonder what the "compute cost" of these new functions is?

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

You are right. Its still in preview mode but you can try it on Azure SQL right now.

These functions cause index scan. I have not done deep analysis, but I am assuming it will similar to any scan operation.

I dont imagine this type of processing being done on a live OLTP system. More likely a read only DB or some type of warehouse.

A question I have: I wonder if column store indexes would help with the efficiency of this type of processing.
