Upgrading from Previous Versions

In-place Upgrade Side-by-side Upgrade

• Easier, mostly automated • More granular control over process

• System data upgraded • Can be used to perform test migration

• No additional hardware • Relatively straightforward rollback

• No change to applications • Can leverage failover/switchover

SalesOrderID INTEGER PRIMARY KEY NONCLUSTERED,OrderDate DATETIME NOT NULL,CustomerID INTEGER NOT NULL,ProductID INTEGER NOT NULL,INDEX ix_SalesOrders_OrderDate CLUSTERED (OrderDate)

);

In-Memory Database Capabilities

What ‘s In-Memory Database

• The Buffer Pool Extension

•Columnstore Indexes

•Memory-Optimized Tables

What Is the Buffer Pool Extension?

Data files(Disk)

Buffer cache(RAM)

Buffer cache extension(SSD)

Pages

Clean Pages

• Extends buffer cache to non-volatile storage

• Improves performance for read-heavy OLTP workloads

•SSD devices are often more cost-effective than adding physical memory

•Simple configuration with no changes to existing applications.

Configuring the Buffer Pool Extension

• Enable using ALTER SERVER CONFIGURATION

• To Reconfigure, disable and then re-enable

ALTER SERVER CONFIGURATIONSET BUFFER POOL EXTENSION ON(FILENAME = 'E:\SSDCACHE\MYCACHE.BPE',SIZE = 50 GB);

What Are Columnstore Indexes?

• In-memory, compressed data in pages based on columns instead of rows

Row Store Column Store

Clustered and Non-Clustered Columnstore Indexes

•Clustered Columnstore Indexes

SQL Server 2014 Enterprise, Developer, and Evaluation Edition Only

Includes all columns in the table

Only index on the table

Updatable

•Non-Clustered Columnstore Indexes

Includes some or all columns in the table

Can be combined with other indexes

Read-Only

What Are Memory-Optimized Tables?

•Defined as C structs, compiled into DLLs, and

loaded into memory

•Can be persisted as filestreams, or non-durable

•Do not apply any locking semantics

•Can be indexed using hash indexes

•Can co-exist with disk-based tables

•Can be queried using Transact-SQL

•Cannot include some data types, including text,

image, and nvarchar(max)

•Do not support identity columns or foreign key

constraints

Memory-Optimized Table Scenarios

•Optimistic concurrency optimizes latch-bound

workloads:

• Multiple concurrent transactions modify large numbers

of rows

• A table contains “hot” pages

•Applications should handle conflict errors:

• Write conflicts

• Repeatable read validation failures

• Serializable validation failures

• Commit dependency failures

Querying Memory-Optimized Tables

•Query Interop

• Interpreted Transact-

SQL

• Enables queries that

combine memory-

optimized and disk-

based tables

•Native Compilation

• Stored procedure

converted to C and

compiled

• Access to memory-

optimized tables only

Memory-Optimized Tables

Disk-BasedTables

Tab1 Tab2 Tab3 Tab4

Transact-SQL

SELECT t1.col1, t3.col2FROM Tab1 t1JOIN Tab2 t2ON t1.Col1 = t2.col1;

Query Interop

Native Compilation

CREATE PROCEDURE…

#define __inHRESULT hkp_(…

0110101101

Translate to C

Compile to DLL

Implementing Security in Microsoft SQL Server 2014

Auditing Enhancements

• Server level auditing included in all editions of SQL Server 2014

• New CREATE SERVER AUDIT options

• Generate user-defined audit events with sp_audit_write

• Extra information in audit logs to discriminate between queries

issued by applications and stored procedures

• Extra columns in auditing catalog views and system functions

CREATE SERVER AUDIT my_auditTO APPLICATION_LOGWITH (QUEUE_DELAY=1000, ON_FAILURE=FAIL_OPERATION)

…

IF APP_NAME() LIKE 'Microsoft SQL Server Management Studio%'BEGIN

EXEC sp_audit_write 1001, 1, N'Statement executed in SSMS'END

Separation of duties enhancement

• Four new permissions• CONNECT ANY DATABASE (server scope)

• IMPERSONATE ANY LOGIN (server scope)

• SELECT ALL USER SECURABLES (server scope)

• ALTER ANY DATABASE EVEN SESSION (database scope)

• Main benefit• Greater role separation to restrict multiple DBA roles

• Ability to create new roles for database administrators who

are not sysadmin (super user)

• Ability to create new roles for users or apps with specific

purposes

•Software Installer: • Specific Active Directory Windows user account enabled during installation and

disabled when not doing installation

• Instance Identity Manager:• Can be designated as server role (SQL Server 2012 or above)

• Enable ALTER ANY LOGIN, ALTER ANY SERVER ROLE permissions

•Highest-level DBA:• Can be designated as server role (SQL Server 2012 or above)

• Enable CONTROL SERVER permission but disable ALTER ANY LOGIN, ALTER ANY

SERVER ROLE, IMPERSONATE ANY LOGIN permissions

• Disable EXECUTE/SELECT/INSERT/UPDATE/DELETE on a per-database schema or

table level

• Or Disable SELECT ALL USER SECURABLES permission combined with disabling

EXECUTE permission because of ownership chaining
