SQL Server 2014 and the Data Platform

In-Memory Built-In Average 10x faster for new and existing SQL Server apps Secure & Scalable Most secure with enterprise scale using Windows Server High Availability The 9’s you need, with AlwaysOn Mission Critical Support Live support designed for mission critical solutions

In-Memory Built-In

Microsoft In-Memory Technologies In-Memory Analytics in PowerPivot for Excel In-Memory Analytics in SQL Server Analysis Services In-Memory Columnstore Index in SQL Server 2012, Fast Track Data Warehouse, and Parallel Data Warehouse StreamInsight In-Memory OLTP In-Memory Columnstore Index (in SQL Server 2014)

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 In-Memory for OLTP

9 Why Hekaton (XTP)?

SQL Server Integration Same manageability, administration & development experience Integrated queries & 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, B-trees Stream-based storage T-SQL Compiled to Machine Code T-SQL compiled to machine code via C code generator and VC Invoking a procedure is just a DLL entry-point Aggressive compile-time Steadily declining memory price, NVRAM Many-core processors Stalling CPU clock rateTCO Hardware trends Business In-Memory OLTP – Architectural Pillars Hybrid engine and integrated experience High performance data operations Efficient business- logic processing Customer Benefits Architectural Pillars Drivers High Concurrency Multi-version optimistic concurrency control with full ACID support Core engine uses lock- free algorithms No lock manager, latches or spinlocks Frictionless scale- up

Fast execution for data warehouse queries Speedups of 10x and more No need for separate base table Saves space Data can be inserted, updated, or deleted Simpler management Eliminate need for other indexes Saves space and simpler management More data types supported Removes many limitations from non-clustered columnstores in SQL Server 2012 Columnstores: clustered and updatable (The next generation)

Comparing space savings (101-million row table and index space)

Secure

Separation of Duties Enhancements 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

SSD Buffer Pool Extension and scale up What’s being delivered Use of non-volatile drives (SSD) to extend buffer pool NUMA-Aware large page and BUF array allocation Main benefits BP extension for SSDs Improve OLTP query performance with no application changes No risk of data loss (using clean pages only) Easy configuration optimized for OLTP workloads on commodity servers (32 GB RAM)

Online Operations Enhancements What’s being delivered Single partition online index rebuild Managing Lock Priority for table SWITCH and online index rebuild Built-in diagnostics Main benefits Increased concurrency and application availability New partition-level granularity for online index rebuild enables lower resource (CPU/memory) usage for customers who need uninterrupted access Provide customers with greater control over impacting running transactions if using switch partition or online index rebuild commands
