Fast Containers: High-Performance C++23 Header-Only Library with Optimized B+Tree Implementation
By
mattgodbolt
Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
Fast Containers is a high-performance header-only C++23 container library focused on x86-64 platforms, currently featuring a fast B+Tree implementation. The library offers significant performance improvements over industry standards for large trees, with benchmarks showing up to 2x faster performance than Abseil's btree for certain workloads. Key advantages include better cache locality, reduced memory overhead, and optimized operations for large datasets. The project is a work in progress with active development focused on cleaning up the implementation.
Key quotes
· 5 pulledHigh-performance header-only container library for C++23 on x86-64.
The B+tree implementation provides significant performance improvements over industry standards for large trees.
For some workloads with large trees, we've observed up to 2x faster performance than Abseil's btree.
Key advantages over Abseil's btree: better cache locality, reduced memory overhead, and optimized operations for large datasets.
Work in progress: This is a work in progress. I don't have plans for major changes to the B+tree currently, but am actively cleaning up the implementation.
