In-Memory OLTP in SQL Server 2014 or later is a powerful engine integrated into the SQL Server Engine, optimized for Online Transaction Processing (OLTP). In-Memory Optimization in SQL Server, has certain characteristics and can help increasing performance in a great number of scenarios.
A Short Description of the SQL Server In-Memory OLTP Technology
If I was about to describe this technology in two simple sentences I would do so with the below:
- It eliminates both locks and latches with an optimistic multi-version concurrency control mechanism.
- It introduces memory-optimized tables and natively-compiled stored procedures.
But In-Memory Optimization achieves significant speedups so why say it depends”?
Best-Suited Workload Types for In-Memory Optimization in SQL Server
- High Data Insert Rate
- Examples: Smart Metering, System Telemetry
- Read Performance and Scale
- Example: Social Network Browsing
- Compute Heavy Data Processing
- Examples: Manufacturing supply chains or retailers
- Low latency Execution
- Examples: Online Gaming Platforms, Capital Markets
- Session State Management
- Example: Managing sessions (i.e. user requests, etc.) for a heavily-visited websites
This of course does not mean that other workload types that are not in the above list cannot benefit from In-Memory Optimization but for them a more thorough investigation/study will be required.
