WHAT’S NEW IN SQL SERVER 2014

• Database Engine• In-Memory OLTP (Hekaton)

• AlwaysOn Enchancements

• Columnstore Indexes

• Analysis Services and BI• SSDT for BI

• Power View for MD Models

• Integration Services

• Reporting Services

ARM TOOL

BUFFER POOL EXTENSION

• The buffer pool extension size can be up 32 times of RAM size

• Recommend a ratio between the size of the physical memory (max_server_memory) and the size of the buffer pool extension of 1:16 or less. • A lower ratio in the range of 1:4 to 1:8 may be optimal.

• Enterprise Edition only

SETTING BUFFER POOL EXTENSION OPTIONS

ALTER SERVER CONFIGURATION SET BUFFER POOL EXTENSION ON (FILENAME = 'F:\SSDCACHE\Example.BPE', SIZE = 50 GB);

GO

ALTER SERVER CONFIGURATION SET BUFFER POOL EXTENSION OFF; GO

BACKUP AND RESTORE ENHANCEMENTS

• SQL Server Backup to URL

• Encryption for Backups • AES 128, AES 192, AES 256, and Triple DES.

• You must use either a certificate or an asymmetric key to perform

encryption during backup

• Screen Cast on SQLschool.gr http://bit.ly/1coQOM0

• SQL Server Managed Backup to Windows Azure

SQL SERVER & WINDOWS AZURE

• SQL Server Data Files in Windows Azure • Enables native support for SQL Server database files stored as Windows

Azure Blobs.

• This feature allows you to create a database in SQL Server running in on-

premises or in a virtual machine in Windows Azure with a dedicated

storage location for your data in Windows Azure Blob Storage.

• Host a SQL Server Database in a Windows Azure Virtual Machine• Use the Deploy a SQL Server Database to a Windows Azure Virtual

Machine Wizard to host a database from an instance of SQL Server in a

Windows Azure Virtual Machine.

DELAYED DURABILITY

• Fully durable transaction • commits are synchronous

• report a COMMIT as successful and return control to the client only after

the log records for the transaction are written to disk.

• Delayed durable transaction • commits are asynchronous

• report a COMMIT as successful before the log records for the transaction

are written to disk.

• Delayed durable transactions become durable when the transaction log

entries are flushed to disk.

USE DELAYED TRANSACTION DURABILITY

• You can tolerate some data loss. • for example, where individual records are not critical as long as you have

most of the data, then delayed durability may be worth considering

• You are experiencing a bottleneck on transaction log writes. • if your performance issues are due to latency in transaction log writes, your

application will likely benefit from using delayed transaction durability.

• Your workloads have a high contention rate. • if your system has workloads with a high contention level much time is lost

waiting for locks to be released.

• Delayed transaction durability reduces commit time and thus releases locks faster which results in higher throughput.

DELAYED DURABILITY CODE SAMPLE

CREATE PROCEDURE <procedureName> … WITH NATIVE_COMPILATION, SCHEMABINDING, EXECUTE AS OWNER AS BEGIN ATOMIC WITH ( DELAYED_DURABILITY = ON,

TRANSACTION ISOLATION LEVEL = SNAPSHOT, LANGUAGE = N'English' …

) END

SELECT … INTO

• The SELECT … INTO statement is improved and can now operate in parallel.

• The database compatibility level must be at least 110.

SECURITY ENHANCEMENTS

• CONNECT ANY DATABASE Permission• Grant it to a login that must connect to all databases that currently exist

and to any new databases that might be created in future.

• Does not grant any permission in any database beyond connect.

• IMPERSONATE ANY LOGIN Permission• When granted, allows a middle-tier process to impersonate the account of

clients connecting to it, as it connects to databases.

• When denied, a high privileged login can be blocked from impersonating other logins.

• SELECT ALL USER SECURABLES Permission• When granted, a login such as an auditor can view data in all databases

that the user can connect to
