Conclusions first: InnoDB in-memory workloads started paying for LRU management in 10.5, a performance regression, and I think the reason is that a clock, which was meant to say “eviction has started”, began ticking much earlier. A minimal fix would bring back the old meaning of the clock. The fix that we pushed tries to do more: it takes buf_pool.mutex out of the LRU promotion on a page access, not only for in-memory workloads. […]

MariaDB Foundation: Auto‑Generated User Properties in TAF 4.0 — The Piece for Ensuring Full Test Reproduction
TAF’s reproducibility story just gained its most important upgrade: every test case now produces a fully resolved, auto‑generated user properties file.
This file captures exactly what the run used — not what the user intended, not what was passed in, but the final, authoritative configuration TAF executed. It removes ambiguity, eliminates hidden dependencies, and makes every test case a fully self‑describing artifact.
This feature builds directly on the work introduced in the previous blog, where TAF gained support for embedding […]
