MySQL 9.7 introduces a long-requested improvement: Child table triggers are executed during SQL-layer foreign key cascades. Historically, cascades executed inside InnoDB did not invoke child table triggers, which created gaps in auditing, derived data maintenance, and observability. When a parent row change triggered cascading changes in child tables, those child table triggers were not executed. This […]

Best practices for MySQL customers and users in an AI-accelerated security landscape: A practical guide to hardening MySQL and the environment around it Oracle recently described how AI is transforming vulnerability detection and response. The latest generation of AI is increasing the speed and scale at which vulnerabilities can be identified and remediated. Oracle is […]

Introduction Replication performance depends on every stage in the pipeline, from the source database to transport and ultimately to commit on the replica. On the replica side, much of that performance comes down to how efficiently changes are read, scheduled, and applied under real operational pressure. In practice, that directly affects steady-state lag, backlog recovery […]

On April 21, 2026, our third public discussion continued the conversation around transparency, participation, and the future of MySQL. Building on the momentum from earlier sessions, the discussion focused on progress and improvements to increase community transparency and practical ways for community members to get involved. At the center of the discussion was the MySQL […]

When people ask me how to tune MySQL, they usually mean, “Which variables should I change in my.cnf?” (the MySQL configuration file) That certainly is a reasonable place to start, because most day-to-day performance tuning really is driven by MySQL itself: memory allocation, redo flushing, connection handling, temporary tables, and InnoDB I/O behavior. But the […]

Overview Some MySQL distribution packages, such as the generic Linux build, bundle an OpenSSL dependency within the same .tar.gz archive. With the new MySQL 8.0.46, 8.4.9 and 9.7.0 releases, we are upgrading those bundled packages from using OpenSSL 3.0 to the new OpenSSL 3.5 LTS branch. Native OS packages, such as .rpm and .deb, continue […]

Following the strong participation in the first two editions of our Public MySQL Community Discussion webinar series, we’re excited to invite you to Edition #3. These sessions are part of our ongoing commitment to increase transparency, strengthen collaboration, and make it easier for the community to provide input that helps shape the evolution of MySQL’s. […]

In 2025, MySQL celebrated its 30th anniversary—and to mark the milestone, Oracle University (together with the MySQL Community team) offered free MySQL training and free certification exams from April 20 through July 31, 2025.  The goal was simple: make it easy for developers, DBAs, architects, and newcomers to build practical skills and validate them with […]

Oracle was proud to sponsor and participate in TEDAI San Francisco, a sold-out event that brought together over 1,200 attendees from across industries to explore, debate, and celebrate the transformative potential of artificial intelligence. Through a mix of key panels, a 48-hour hackathon, and thought leadership engagement, Oracle showcased its commitment to responsible AI innovation […]

MySQL observability is essential in modern enterprises, whether you run a few critical databases or operate at massive scale. With the right real‑time monitoring, teams reduce MTTD/MTTR, avoid cascading failures, and continuously track workload health—CPU, memory, I/O, buffer pool efficiency, session contention, transaction/replication lag, error rates, and query latency. This Grafana monitoring template helps teams […]
