New high-performance, memory-optimized OLTP engine integrated into SQL Server and designed for

modern hardware trends

Integrated into SQL Server relational database

Full ACID support

Memory-optimized indexes (no B-trees or buffer pools)

Non-blocking multiversion optimistic concurrency control (no locks or latches)

T-SQL compiled to native code

Customer benefits

• Low latency

• Up to 10x improvement in performance

• 2–5x improvement in scalability

• Takes advantage of investments in SQL Server

SQL Server integration

• Same manageability,

administration, and

development experience

• Integrated queries and

transactions

• Integrated HA and

backup/restore

Main-memory

optimized

• Optimized for in-memory

data

• Indexes (hash and range)

exist only in memory

• No buffer pool

• Stream-based storage for

durability

High concurrency

• Multiversion optimistic

concurrency control with full

ACID support

• Core engine uses lock-free

algorithms

• No lock manager, latches, or

spinlocks

T-SQL compiled to

machine code

• T-SQL compiled to machine

code via C code generator

and Visual C compiler

• Invoking a procedure is just

a DLL entry-point

• Aggressive optimizations at

compile time

• What’s being delivered

• Increase number of secondaries from four to eight

• Increase availability of readable secondaries

• Support for Windows Server 2012 CSV

• Enhanced diagnostics

• Main benefits

• Further scale out read workloads across (possibly geo-distributed) replicas

• Use readable secondaries despite network failures (important in geo-distributed environments)

• Improve SAN storage utilization

• Avoid drive letter limitation (max 24 drives) via CSV paths

• Increase resiliency of storage failover

• Ease troubleshooting

SQL Server Oracle MySQL DB2

• What’s being delivered

• Three new permissions (CONNECT ANY DATABASE, IMPERSONATE ANY LOGIN, and SELECT ALL

USER SECURABLES)

• Main benefit

• Greater role separation

• 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

Examples:

1. Database administrators but cannot see user data

2. Database administrators but cannot modify logins

3. Database administrators but cannot impersonate any logins

4. New roles (for example, auditors) to read all data but not database administrators

5. New roles to read all metadata for monitoring purposes (for example, SCOM) but cannot see user

data

6. New roles for middle tier app to impersonate any login except sa, sysadmin, or other high

privilege logins
