DataMountain: .NET data warehousing that beats C++ performance

From the creator

Databases and high-end data processing are commonly thought of as the realm of "systems languages" such as C, C++, and Rust. Pansynchro Technologies is looking to change that. Our new data warehouse service, DataMountain, uses the .NET community's intense performance optimizations of recent years to their fullest, producing blazing-fast SQL results that even manage to edge out Clickhouse on their own benchmarks in some cases. This session will go over some of the tricks that went into building this system, and how we used .NET code generation, high-performance code such as Spans and Vectors, and some tricks that just don't exist in systems languages, to build a .NET data warehouse with top-tier performance. 🎥 See more from .NET Conf: https://aka.ms/dotnetconf-playlist 🔗 Links: .NET 10 — The most intelligent and unified .NET yet: https://aka.ms/dotnet10/ .NET Aspire 13 — Simplified orchestration for cloud-native apps: https://aka.ms/aspire13/announcement ASP.NET Core 10 — Modern, secure, and full-stack web development: https://aka.ms/asp/dotnet/2025 .NET MAUI 10 — Build beautiful apps on every platform: https://aka.ms/dotnet/maui/2025 C# 14 — A more expressive and productive language: https://aka.ms/csharp14/announcement/2025 F# 10 — Safer, faster, and more functional than ever: https://aka.ms/fsharp10/2025/announcement Visual Studio 2026 — Faster, smarter, and built for the future: https://aka.ms/visualstudio2026/announcement 🎙️ Featuring: Mason Wheeler Connect with
