I have to share data between Azure A   and Azure B . using unity catalog and delta sharing.
Every Time Data comes to Azure A, The same Data can be read by AzureB.
How to handle Incremental Load. for change records I think I need to use Merge Statement.
May someone please help me with detailed steps  on how to implement it in production.
 
 
Kindly share your Knowledge.
