3. WHAT WE’LL (TRY TO) COVER: Database Engine Improvements  ColumnStore Improvements  In-Memory OLTP  Query Store  Temporal Tables  Always Encrypted  Stretch Database  Live Query Statistics  Row Level Security  Dynamic Data Masking SLIDES DEMOS! Whirlwind tour

4. WHAT WE’LL SKIP  Reporting Improvements  Analysis Services Improvements  Integration Services Improvements  Looking to CTP3 for more soon…  You can find out more at: http://bit.ly/sql2016-whats-new http://bit.ly/sql2016-whats-new

5. HOW DO I SQL 2016?  30 Day Azure Trial!  MSDN? You get free Azure to learn and test.  If you can use fill in a web form and use Remote Desktop, you can spin up virtual machines in the cloud and learn without downloading or installing.  Windows 10, Server 10, Visual Studio 2015 previews are also available.  Why not?

6. COLUMNSTORE IMPROVEMENTS  Whitepaper:  http://bit.ly/sql2016-columnstore http://bit.ly/sql2016-columnstore

7. Columnstore Index Feature SQL Server 2012 SQL Server 2014 SQL Server 2016 (CTP2) Azure SQL Database Batch execution for multi-threaded queriesyes Batch execution for single-threaded queriesyes Archival compression option.yes Snapshot isolation and read-committed snapshot isolationyes Specify columnstore index when creating a table.yes AlwaysOn supports columnstore indexes.yes AlwaysOn readable secondary supports read-only columnstore indexes.yes AlwaysOn readable secondary supports updateable columnstore indexes.yes Read-only nonclustered columnstore index on heap or btree.yes yes 1 Updateable nonclustered columnstore index on heap or btreeyes Additional btree indexes allowed on a heap or btree that has a columnstore index.yes Updateable clustered columnstore index.yes Btree index on a clustered columnstore index.yes Columnstore index on a memory-optimized table.Yes! Nonclustered columnstore index definition supports using a filtered condition.yes

8. IN MEMORY OLTP IMPROVEMENTS  Whitepaper: http://bit.ly/sql2016-in-memory-oltp http://bit.ly/sql2016-in-memory-oltp  Aaron Bertrand Blog: http://sqlperformance.com/2015/05/sql-server- 2016/in-memory-oltp-enhancements http://sqlperformance.com/2015/05/sql-server- 2016/in-memory-oltp-enhancements

9. KEY IMPROVEMENTS FOR IN MEMORY OLTP Recommended maximum size for in memory table goes from 256MB->2TB Collations besides BIN2 allowed for columns in indexes (advised they don't perform as well) ALTER TABLE can be used on memory-optimized tables to add, drop or alter columns, or to add, drop or rebuild indexes. ALTER PROCEDURE can be used on natively compiled stored procedures Native compiled procedures allows additional syntax (LEFT JOIN, SELECT DISTINCT, UNION, all math functions) Better scaling with additional sockets AlwaysOn replicas see in-memory data changes undelayed. Improved garbage collection

10. COLUMNSTORE + IN MEMORY OLTP = OPERATIONAL ANALYTICS  In-memory, updateable, non-clustered columnstore index over either disk-based or in-memory tables.  Learn more:  Sunil Agarwal on Data Exposed: https://channel9.msdn.com/Shows/Data-Exposed/SQL- Server-2016-Operational-Analytics https://channel9.msdn.com/Shows/Data-Exposed/SQL- Server-2016-Operational-Analytics  Sunil’s Ignite 2015 Presentation: http://channel9.msdn.com/Events/Ignite/2015/BRK4552 http://channel9.msdn.com/Events/Ignite/2015/BRK4552

11. QUERY STORE  Demo  Best 2016 Feature?

12. TEMPORAL TABLES  Demo  Look back in time at your data  Table Templates  Works along with SQL AUDIT for complete data change history (WHO,WHAT,WHEN)  New Time Travel SQL Syntax!

13. Source: https://msdn.microsoft.com/en-us/library/dn935015%28v=sql.130%29.aspx Syntax for Querying Temporal Data SYNTAX FOR QUERYING TEMPORAL DATA ExpressionQualifying RowsDescription AS OF SysStartTime date_time Returns a table with single record for each row containing the values that were actual (current) at the specified point in time in the past. Internally, a union is performed between the temporal table and its history table and the results are filtered to return the values in the row that was valid at the point in time specified by the parameter. The value for a row is deemed valid if thesystem_start_time_column_name value is less than or equal to the parameter value and thesystem_end_time_column_name value is greater than the parameter value. FROM TO SysStartTime start_date_time Returns a table with the values for all record versions that were active within the specified time range, regardless of whether they started being active before the parameter value for the FROM argument or ceased being active after the parameter value for the TO argument. Internally, a union is performed between the temporal table and its history table and the results are filtered to return the values for all row versions that were active at any time during the time range specified. Records that became active exactly on the lower boundary defined by the FROM endpoint are included and records that became active exactly on the upper boundary defined by the TO endpoint are not included. BETWEEN AND SysStartTime start_date_time Same as above in the FOR SYSTEM_TIME FROM TO description, except the table of rows returned includes rows that became active on the upper boundary defined by the endpoint. CONTAINED IN(, ) SysStartTime >= start_date_time AND SysEndTime <= end_date_time Returns a table with the values for all record versions that were opened and closed within the specified time range defined by the two datetime values for the CONTAINED IN argument. Records that became active exactly on the lower boundary or ceased being active exactly on the upper boundary are included.

14. ALWAYS ENCRYPTED  Demo  Data encypted in flight and at rest  Better than TDE, encrypted for all users, even admins.  Requires.Net 4.6! (As does SSMS 2016)  Source (MSDN Blog): http://bit.ly/sql2016-always- encrypted-walkthru http://bit.ly/sql2016-always- encrypted-walkthru

15. STRETCH DATABASE  Demo  Interesting solution to where to put that historical data without taking up valuable disk space or prolonging backups.  Queries don’t change, SQL combines local and ‘stretched’ data.  Looking forward to additional controls here.

16. LIVE QUERY STATISTICS  Demo  Works with debugging!

17. ROW LEVEL SECURITY  Demo  Already in V12 version of Azure SQL Database  Extremely customizable, granular control over data access on row by row level.  Source: Francesco Cogno Blog http://blogs.msdn.com/b/frcogno/ http://blogs.msdn.com/b/frcogno/

18. DYNAMIC DATA MASKING  Demo  Already in V12 version of Azure SQL Database  Effectively protects sensitive data in application layer, not effective for admins or users with SELECT rights.

19. OTHER STUFF  SELECT * FROM Table FOR JSON AUTO  PolyBase  Managed Backup & Backup to Azure Improvements (Backup to Blob)  Multiple TempDBs upon install  Online ALTER COLUMN  Find out more: http://bit.ly/sql2016-whats-new-db-engine

20. GUESSES FOR NEXT CTP:  Bug fixes and feature improvements on CTP2  PowerBI functionality for onsite SQL Servers?  R for Data Analysis  Mobile Reporting?  ???
