3. SQL Server 2016 - Overview

4. How Microsoft develop SQL
Cloud-first but not cloud-only
Many interesting and compelling on-premises  cloud scenarios
Think of APS as the “evolution” of Microsoft's current SQL Server Parallel Data Warehouse product

6. What’s New?
 Live Query Statistics
 Query Store
 Temporal Tables
 Stretch Database
 Availability Groups
 T-SQL Extras
 Others
 Others – Business Intelligence

7. Live Query Statistics
 View the live execution plan of an active query
 Because this data is available in real time without needing
to wait for the query to complete, these execution
statistics are extremely useful for debugging query
performance issues

8. Live Query Statistics
 Not Supported:
 Queries using columnstore indexes
 Queries with memory optimized tables
 Natively compiled stored procedures

9. Query Store
 Provides database administrators with insight on query
plan choice and performance
 Stores history of queries, plans, and runtime statistics
 Has graphical interface! - Important for adoption

10. Query Store
Durability latency controlled by DB
option
DATA_FLUSH_INTERNAL_SECONDS
Compile
Execute
Plan store
Runtime
stats
Query
Store
schema
Stores all plan choices and performance metrics
Works across restarts / upgrades / recompiles

11. Query Store

12. Query Store
 Easy to enable either T-SQL or right-click per database
option
 ALTER DATABASE AdventureWorks2012 SET
QUERY_STORE = ON;
 To look at current options
 sys.database_query_store_options

13. Temporal Tables
 Tracking and analyzing changes in data is often important
 Easy to use and setup
 System versioned tables – SQL Server keeps track of the versioning
 Provides correct information about stored facts at any point in time, or
between two points in time using BETWEEN
 Standard Edition feature

14. Temporal Tables
 Simple syntax

15. Temporal Tables
 Temporal tables work by creating a new system versioned table
Temporal table (actual data)
* Old versions
History table

16. Stretch Database
 Per table archiving rows into the PaaS service Azure SQL
v12 Database
 Creates a database such as
 Creates a Standard service tier at the S3 performance
level 250GB maximum size (~£92/month)
 Blurring the line between on premise and cloud -
achieving a hybrid solution

17. Stretch Database
 Not Supported:
 Replicated, Memory-optimized or Change Data Capture
tables
 geometry, geography, XML, UDT types
 UPDATE or DELETE operations!
 ALTER TABLE operations
 Uniqueness is not enforced for UNIQUE constraints and
PRIMARY KEY constraints

18. Availability Groups
 Although a niche enhancement - Load-balancing of read-
intent connection requests is now supported across a set
of read-only replicas
 Much more relevant for our infrastructure team
management - Group Managed Service Accounts are now
supported for Always On Failover Clusters - Windows
Server 2012 R2, an update is required to avoid temporary
downtime after a password change!
 Support for distributed transactions and the distributed
transaction co-ordinator on Windows Server 2016

19. Azure Secondaries
 You can now have readable secondaries when using PaaS
under any tier and therefore can be used to offload read-
only workloads such as reporting jobs.
 With the addition of Azure Active Directory customers
can manage user access to both primary and all secondary
databases and eliminating the need for managing
credentials in databases all together.

20. T-SQL Extras
 A new query hint NO_PERFORMANCE_SPOOL can prevent
a spool operator from being added to query plans. This
can improve performance when many concurrent queries
are running with spool operation
 You can now TRUNCATE TABLE WITH PARTITIONS to only
truncate specified partitions of a table

21. Others
 JSON Support – using FOR JSON like FOR XML
 Backup to Azure using block blobs – more space, allows
striping
 tempdb - files automatically provisioned
 Option in installation for setting up Instant File
Initialisation
 Maintenance Plans – Have many more options including
index fragmentation level options

22. Others
 Check for Updates! in Management Studio

23. Others
 New report replaces the need to use the Management Data Warehouse
to analyze which tables and stored procedures are candidates for in-
memory optimization
 New Transaction Performance Analysis Overview report

24. Others
 Azure SQL Database PaaS (Platform as a Service) solution
now has powerful Premium tiers – P11 with 1750 DTU
(Database Throughput Unit)
 DTU is a blended measure of CPU, memory, reads, and
writes
 You can quickly use the images to build an IaaS SQL Server
2016 test VM in Azure to test and learn these new
technologies

25. Others – Business Intelligence
 R now in Business Intelligence
 Polybase included – previously only in PDW (Parallel Data
Warehouse)
 Integration Services (SSIS) fans will be happy to know that
designer now supports previous versions.
 Many new features in Reporting Services including KPI’s
