7. Is Stretch Database for you?
Decision Maker
DBA
I have to keep transactional data for a long time
The size of my tables is getting out of control
Sometimes I have to query the cold data
My users say that they want access to cold data, but they only rarely use it
I have apps, including older apps, that I don’t want to update
I have to keep buying and adding more storage
I want to find a way to save money on storage
I can’t backup or restore such large tables within the SLA

Check constraints
Foreign keys that references the table
