>>in-memory optimized tables/columnstore indexes is definitely a big direction Microsoft is going with SQL Server.
I heard that SQL Server 2019 will have the most amazing new ability: spooling those in-memory optimized tables to disk. ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
