MariaDB Foundation: Reproducing and Validating MDEV‑37992 with TAF
Thanks to Mark Callaghan for filing MDEV‑37992. This regression only appears under specific LRU and buffer‑pool conditions, and requires a memory‑resident workload to expose.
Using TAF, I reproduced the issue across 11.8, 12.3, and 13.1 using both parent commits and patched commits from MDEV‑33966. The fix restores expected throughput in all branches.
The workload used was POINTS‑COVERED‑PK with 10M rows × 8 tables, 40 threads, warmup enabled, and a 90G buffer pool. TAF’s warmup iteration, rest detection, and stable‑state perf […]

MariaDB Plugins Beyond C++: What the Community Told Us

Which language would you use to write MariaDB plugins?
The question related to MDEV-40189 (Support plugins written in various languages), an idea we introduced earlier this summer to lower the barrier to MariaDB plugin development by supporting languages other than C and C++.
The poll is now closed, and 2,090 people voted.
And the results are interesting.
Python and Rust lead, but there is no single winner
Python takes first place […]

Tell us how to DROP USER!
Shortly, we will start coding a task, for which we would appreciate your input: How would you like to DROP USER?
Why do we ask?
DROP user (originating in MySQL in 2004) always used to just drop the account from the privilege tables, but left all existing connections active. You can argue that this was questionable in 2004, but it’s really unexpected and confusing in 2025, with MariaDB being ubiquitous as it is.
So now we’re considering changing it.
But […]
