●●●BangerBig BrainWizardry

Git-like branching for columnar data with DuckDB-beating benchmarks from pure JVM.

Strengths
  • •Copy-on-write branching enables O(1) dataset forks with structural sharing.
  • •SIMD execution via Java Vector API needs no native compilation.
  • •PostgreSQL wire protocol means existing clients connect immediately.
Weaknesses
  • •JVM-based may concern teams standardizing on native or Go tooling.
  • •Long-term integration with Datahike's Datalog planner remains unfinished.

Benchmarking Apple Silicon unified mem for GPU-accelerated SQL analysis

The repo does one practical thing well: quantify the real-world impact of Apple Silicon's unified memory on analytics by running six TPC-H queries plus a GPU-favorable QX and shipping the raw charts and code. It's specific and empirical — you get MLX vs NumPy vs DuckDB numbers and PNGs, not just hand-wavy claims — but it's narrowly scoped to M4 hardware and small-ish scales, so its conclusions are useful for experimentation rather than sweeping generalization.
