SQL Server 2014 will offer Clustered Columnstore Indexes. These will offer the performance and compression benefits of column-oriented storage without the need to restrict the underlying table to read-only access.
Originally this report was titled “Natively Compiled Queries”, but that doesn’t do justice to how deep this runs. When a memory optimized table is created, SQL Server will create a DLL specifically for that table. All data access for the table, including indexes, occurs through this DLL.
SQL Server 2014’s Memory Optimized Tables handle indexes very differently than traditional tables. First and foremost, you must have at least one index and cannot have more than eight indexes. Only the primary key can be marked as unique and don’t even think about foreign keys or filtered indexes.
In SQL Server 2014 Microsoft will be unveiling its lock-free technology known as Memory Optimized Tables. Using a new storage and query subsystem, these represent a radical departure from traditional database design.

Being clever about system architecture in advance is hard. Scaling successfully is more about being clever with metrics and introspection, creating efficient build and provisioning processes and being comfortable with radical change. These are some of the keys to scaling at Dropbox according to Rajiv Eranki in his recent presentation at the 2013 RAMP Conference.
IBM has relaxed the memory restrictions on the free version of their flagship database. Version 10.5 of DB2 Express-C can now use up to 16 GB of RAM. The product already allowed for unlimited database sizes on disc but is limited to a single socket (2 cores).
