Still on MariaDB 10.6? Why your next upgrade is a security decision
Last week was about PHP. This week, check your database.
On 21 October 2026, the PHP project shipped emergency fixes for two critical remote code execution flaws, CVE-2026-109618 and CVE-2026-109619, known together as PHP2Shell. Exploit details leaked before the patch, attacks started within hours, and the only real fix was to upgrade PHP or shut down your website. Anyone running PHP 7 or earlier had no official patch at all.
If you run a hosting platform, you probably spent last […]

The Man Who Benchmarks MariaDB Against the World
Jonathan Miller has spent 27 years in database performance testing. He talks about TAF, the open source Test Automation Framework that benchmarks MariaDB, MySQL and PostgreSQL side by side, configuration provenance, and how to prove your patch made MariaDB faster.

MariaDB Foundation: Exploring TidesDB Performance with TAF
TidesDB now exists inside MariaDB as a pluggable storage engine.
With the TideSQL plugin available, anyone can load TidesDB into a MariaDB server and begin experimenting with it.
But having a plugin is only the first step — you still need a practical, reproducible way to run real workloads against it, that’s where TAF comes in.
This blog exists to give anyone interested in TidesDB a roadmap to the city of benchmarking it — a clear, reproducible starting point for […]

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 […]

Building a Public Performance Change Detection Library for MariaDB
Performance engineering inside a database project is usually private. Teams run internal workloads, investigate changes, fix issues, and move on. The knowledge stays inside the company, and the outside world only sees a benchmark graph or a release note.
I know this pattern well — I spent more than twenty‑six years doing this work for both PervasiveSQL and MySQL.
The investigations were deep, the lessons were real, but almost none of it was visible to the outside world.
The surprises, […]

MariaDB Foundation Adds PostgreSQL to Its Engine‑Agnostic Testing Framework (TAF).
The Test Automation Framework (TAF) was designed so that database makers themselves could create a plugin and integrate their database engine directly into the framework.
TAF provides the structure — lifecycle management, workload execution, profiling, reporting, and reproducible properties files — and each database plugin supplies the engine‑specific logic.
The first two plugins added to TAF were MariaDB and MySQL, proving the model: database vendors can plug their engine into TAF and immediately gain automated installs, structured workloads, concurrency sweeps, […]

Migrating a 500 GB Production MariaDB Database from Amazon RDS to EC2, With a Rollback Path
I always enjoy real production stories where MariaDB is used in demanding environments and the people involved are willing to share the architecture, the challenges, and the decisions made along the way.
Pradip Shah from luroConnect recently documented how his team migrated a 500+ GB production MariaDB database from Amazon RDS to self-managed MariaDB on EC2.
Moving from RDS to EC2 is often expected to bring significant cost savings because you are moving from a fully managed database service to […]

MariaDB Foundation: TAF Now Supports Embedded Database Configuration in User Properties
TAF: One File to Rule Them All
In a one‑on‑one review of TAF with Monty Widenius, the creator of MySQL and MariaDB, he looked at me and said: “I want everything in one user file.”
It was simple, direct, and completely right direction.
TAF’s configuration model had inherited its design from older frameworks — a user properties file and a separate database configuration file.
Monty’s comment cut straight through it. He wanted simplicity — one file that defines everything.
So […]
