Indentity and surrogate key

[Si_7777]

I currently have a Data Warehouse in SQL Server.  We have a database for staging and a database for the Data Warehouse containing dimension and facts.  We use SSIS to ETL the data from legacy to staging and then to the DW.  I am looking to move this into the cloud preferably Fabric.  

Just trying to create fact and dimension tables and have already run into a problem  : 

The IDENTITY Keyword is not supported in the CREATE TABLE statement in this edition of SQL server

Surely this is funamental to how a related DW works whats the solution to work around?

Fabric warehouse is an MPP framework and OLAP (more for analytics purpose)

In case if you want a replicae of SQL server, you can leverage fabric databases rather than fabric warehouse for your use case

Hi @Si_7777 you can also use this approach in Fabric Warehouses, which is what I currently use

Generate unique identifiers in a warehouse table - Microsoft Fabric | Microsoft Learn

As @NandanHegde said, if you need all the functionality of an RDBMS then Fabric SQL Databases have you covered.

Thank you for replying.  I wouldnt say we need to replicate SQL server as such.  I have been tasked with moving our current solution to the cloud and I asssumed Fabric Data Warehousing was the way forward.  We have dimensions and facts currently using SSIS for ETL.
