SQL Server 2016 - Overview
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

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
Live Query Statistics
Not Supported:
Queries using columnstore indexes
Queries with memory optimized tables
Natively compiled stored procedures
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
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
Query Store
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
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
Temporal Tables
Simple syntax
Temporal Tables
Temporal tables work by creating a new system versioned table
Temporal table (actual data)
* Old versions
History table
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
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
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
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.
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
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
Others
Check for Updates! in Management Studio
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
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
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
