About a year ago, we discussed how MyDumper refactored its locking mechanisms to move away from old, rigid flags and transitioned towards more flexible, streamlined execution. Since then, the MyDumper community hasn’t stood still.

In recent releases, the locking architecture was further standardized under a single overarching option: --sync-thread-lock-mode. Along with this modernization came a powerful new safety feature designed to give you lock-free thread synchronization without risking silent inconsistency: SAFE_NO_LOCK (merged in PR #2031).

Let’s explore the new thread-synchronization landscape and break down when you should use each mode.

What is --sync-thread-lock-mode?

Previously, flags like …

With the new LTS (Long Term Support) release of MySQL 9.7.0 https://dev.mysql.com/doc/relnotes/mysql/9.7/en/ , Dynamic Data Masking (DDM) is one of the new features introduced as part of Enterprise Edition.

TL;DR If you use MD5(), SHA1(), or SHA() in MySQL today, start planning the move to SHA2(). Beginning with MySQL 9.6, MD5(), SHA1(), and SHA() are no longer native built-in SQL functions in the server binary. They are available through the Legacy Hashing Component: That component should be treated as a stopgap solution. It gives […]

Upstream MySQL published an out-of-schedule release this week with two high-severity CVE fixes. If you’re running Percona Server for MySQL 5.7 or 8.0 under Extended Lifecycle Support (ELS), the program we previously called Post EOL Support, you don’t have to do anything to qualify for them. We’ve already applied the fixes and re-released the affected ELS builds.

This is the point of ELS. When a major version reaches End of Life (EOL), the community stops shipping patches, but the databases running on it don’t stop mattering. ELS keeps critical bug and security fixes coming for versions that are past their EOL date, so you can stay on 5.7 or 8.0 on your own timeline instead of a deadline someone else set.

What we did

These CVE fixes landed upstream outside the normal cadence. Under ELS, customers are entitled to security fixes for the versions they run, so we pulled the patches into the 5.7 and 8.0 builds and …

Keeping up with the MySQL ecosystem is becoming increasingly challenging. Every release introduces new features, performance improvements, security enhancements, and cloud capabilities. While the official documentation is comprehensive, it is not always easy to quickly identify what really matters.

To help with that, I've published a new edition of my MySQL & MySQL HeatWave Report, covering the most important announcements around MySQL 9.7 LTS and MySQL HeatWave 9.7.

Upstream MySQL published an out-of-schedule release this week with two high-severity CVE fixes. We’ve pulled those fixes into our next builds and are skipping the two versions we had already queued: Percona Server for MySQL 8.4.9 and 9.7.0.

These fixes arrived through Oracle’s new monthly Critical Security Patch Updates (CSPUs), which Oracle announced begin May 28, 2026. CSPUs ship targeted …
