I decided to check if there is still database mirroring option in MS SQL Server 2014
Wow! It works!
However in the screenshot you see a message that new tables “in memory” can not be used together with mirroring.
It’s worth noting that MS SQL Server 2012 already warned of possible termination of this option in future versions of MS SQL Server
Now the same message is also posted on the page of MS SQL Server 2014
It means a good fail-safe solution lives on!
And it is probably going to be depreciated in SQL Server 2018
