UNIQUE AND NOT DULLwww.MyGareth.com Always Encrypted  Protects data at rest and in motion  Encryption key resides with the application  Encryption and Decryption are transparent & happen on application side  Always Encrypted Driver -.NET Framework 4.6

UNIQUE AND NOT DULLwww.MyGareth.com Always Encrypted  Encryption is at the column level, rather than at the database level  Feature-based restrictions:  Temporal tables  Triggers are partially supported  Full-text search  Replication  Change Data Capture  In-memory OLTP  Stretch database

UNIQUE AND NOT DULLwww.MyGareth.com  Flight data recorder (black box) for your database  Query store retains multiple execution plans per query  Collects query text along with all relevant properties  Two stores:  Plan store – persisting execution plan information AND metrics  Runtime statistics store – persisting the statistics information  Catalog views: sys.query_store_plan, sys.query_store_query, sys.query_store_query_text Query Store

UNIQUE AND NOT DULLwww.MyGareth.com  Easily find & fix plan regression  Pinpoint the most expensive queries  Minimise SQL Server upgrade risks  Analyse workload patterns With query store, you can ….

UNIQUE AND NOT DULLwww.MyGareth.com Row-Level Security  Row level access control  Based on user’s group membership or execution context  Restriction logic located at the DB tier rather than at the app tier  Optimizer automatically applies predicate function to queries  Security Predicates:  Filter  Block  Steps:  Create predicate function  Create security policy to bind function to table(s)

UNIQUE AND NOT DULLwww.MyGareth.com Stretch Database  Leverages Azure to store and query archive data  Archives data transparently and securely  Reduced cost, performance gains against current (on-premises) data  Can join across local and remote data  User code will still point to SQL on-premises instance  Run the Stretch Database Advisor EXEC sys.sp_configure N'remote data archive', '1';

UNIQUE AND NOT DULLwww.MyGareth.com Stretch Database

UNIQUE AND NOT DULLwww.MyGareth.com Stretch DB Limitations (CTP 3.0)  Memory-optimized and replicated tables  Tables that contain FILESTREAM data, use Change Tracking or Change Data Capture  Data types such as timestamp, sql_variant, XML, geography or columns that are Always Encrypted  Check, default, or foreign key constraints that reference the table  XML, full-text, spatial, clustered columnstore indexes and indexed views  UPDATE or DELETE statements, CREATE INDEX or ALTER INDEX operations  Limitations:

UNIQUE AND NOT DULLwww.MyGareth.com  Distributed Transaction Coordinator support  Load Balancing for Readable Secondaries  Additional synchronous failover targets – up to 3  Optional setting to fail over based on database failure  Group Managed Service Accounts are fully supported  Improved log transport performance AlwaysOn Enhancements

UNIQUE AND NOT DULLwww.MyGareth.com PolyBase  Introduced in PDW v2  Use T-SQL to access data in Hadoop  Configuration:  Install PolyBase  Choose Hadoop or Azure using sp_configure  Create external data source and file format in SQL  Create external table to reference the data HDFS SQL 2016 Hadoop Results7 2 Map job 5 HDFS blocks DB SQL1 MapReduce

UNIQUE AND NOT DULLwww.MyGareth.com JSON Support  JSON - JavaScript Object Notation.  JSON support is one of the highest ranked requests by customers.  JSON is used primarily to transmit data between a server and web application, as an alternative to XML.  JSON is used in a majority of Web APIs and is growing significantly.  CTP2 – FOR JSON [PATH | AUTO]  CTP3 – OPENJSON, IsJSON ( ), JSON_Value ()

UNIQUE AND NOT DULLwww.MyGareth.com TempDB Enhancements  Trace Flags 1117 & 1118 not required  Setup adds TempDB files = CPU count or 8, whichever is lower  Default initial size is 8MB and the default autogrowth is 64MB  Multiple volumes for TempDB files  Configure TempDB during initial setup
