🚨🚨🚨❌❌❌ SQL BENCHMARK FAILED ❌❌❌🚨🚨🚨Benchmark |
Add PinnedCpuPool/PinnedExecutor: a core-pinned thread pool that overrides spawn_cpu while delegating async I/O to the fallback runtime (tokio). Avoids work-stealing for decode-heavy ops (bitunpacking, FoR, dictionary gather), keeping data cache-local. Expose via RuntimeSessionExt::with_pinned_cpu_pool() and enable it by default in the benchmark SESSION. Fix executor lifetime bug by storing a strong Arc in RuntimeSession alongside the Weak-based Handle. Signed-off-by: Alexander Droste <alexander.droste@protonmail.com>
