In-Memory OLTP – Architectural Pillars
High performance data
operations
Efficient business-logic
processing
Frictionless scale-up
Hybrid engine and
integrated experience
Main-Memory
Optimized
T-SQL Compiled to
Machine Code
High Concurrency
SQL Server Integration
• T-SQL compiled to machine
code via C code generator
and VC
• Invoking a procedure is just
a DLL entry-point
• Aggressive optimizations @
compile-time
• Multi-version optimistic
concurrency control with full
ACID support
• Core engine uses lock-free
algorithms
• No lock manager, latches or
spinlocks
• Optimized for in-memory
data
• Indexes (hash and range)
exist only in memory
• No buffer pool, B-trees
• Stream-based storage
Business
Hardware trends
Steadily declining memory
price, NVRAM
Stalling CPU clock rate
• Same manageability,
administration &
development experience
• Integrated queries &
transactions
• Integrated HA and
backup/restore

Columnstores: clustered and updatable (The next generation)
• 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
