in memory database

Does CUBA support an In-Memory database?

From the documentation of Oracle 12 c it looks like there is no change needed at application level to use the database in memory but for MS SQL Server 2014 a special type of table has to be created (OLTP). That can be done at the database level though. My question is, have anyone used this in-memory database functionality with a CUBA application and is there anything needed to be done for in-memory database at APP development ?
