SQL Server 2016 Coming Soon

Coming Soon to SQL Server 2016

Query Store
The Query Store feature maintains a history of query execution plans with their performance data, and quickly identifies queries that have gotten slower recently, allowing administrators or developers to force the use of an older, better plan if needed. The Query Store is configured at the individual database level.

Polybase
Microsoft has incorporated Polybase into the regular on-premises product. This feature will benefit you if your regular data processing involves dealing with a lot of large text files — they can be stored in Azure Blob Storage or Hadoop, and queried as if they were database tables.

Stretch Database
The basics of Stretch Database are that some part of your tables will be moved into an Azure SQL Database in the cloud. When you query those tables, the query optimizer knows which rows are on your server and which rows are in Azure, and divides the workload accordingly. The query processing on the Azure rows takes place in Azure so the only latency is for the return of the rows over the network.

JSON Support
SQL Server 2016 adds support for Java Script Object Notation (JSON). The way this is implemented in SQL 2016 is very similar to the way XML support is built in with FOR JSON and OPENJSON — providing the ability to quickly move JSON data into tables.

Row Level Security
SQL Server 2016 introduces this feature, which is very useful in multi-tenant environments where you may want to limit data access based on customer ID.  The implementation of RLS in SQL 2016 still has it limits (updates and inserts are not covered), but it is good start on a much-needed feature.

Always Encrypted
SQL Server has long supported both column-level encryption, encryption at rest, and encryption in transit. However these all had to be configured independently and were frequently misconfigured. Always Encrypted is new functionality through the use of an enhanced client library at the application so the data stays encrypted in transit, at rest and while it is alive in the database. Also given Microsoft’s push towards the use of Azure, easy encryption makes for a much better security story.

In-Memory Enhancements
In SQL Server 2016, this feature is improved, supporting foreign keys, check and unique constraints and parallelism. Additionally, tables up to 2TB are now supported (up from 256GB). Another part of in-memory is column store indexes, which are commonly used in data warehouse workloads. This feature was introduced in SQL 2012 and has been enhanced in each version since. In 2016 it receives some enhancements around sorting and better support with AlwaysOn Availability Groups.
