The latest from the MySQL community

A real-world troubleshooting guide showing how MySQL metadata query behavior can cause Tungsten Replicator to appear stalled despite healthy cluster status, with root-cause analysis and preventive configuration recommendations.

Overview OpenSSL 3.5 integrates a number of algorithms resistant to attack by future quantum computers, commonly referred as Post-Quantum Cryptography (PQC). These include: Possibility of storing the vast amounts of TLS encrypted traffic now and decrypting it later once the quantum computers become capable enough is considered a real problem, so the governments and standards […]

We recently tested the PostgreSQL backup tool pg_basebackup and were very impressed with its remote backup functionality, which allows for both physical local and physical remote backups.

This led us to wonder whether a physical remote backup is also possible using the “new” MySQL Server Clone feature, which was introduced in MySQL 8.0.17 (July 2019).

The MySQL Clone operation can be used to create both a local and a remote copy of the database. The original idea behind this feature was likely to automatically create nodes in an InnoDB Cluster (similar to Percona XtraDB Cluster SST).

Terminology used in the clone operation:

• Donor (source database)
• Recipient (destination database)

The clone operation is initiated from the recipient. The data can be cloned to the recipient’s own directory or, alternatively, to a different directory.

“Through transparent roadmaps, community-driven collaboration, contributor programs, and the MySQL Governance model, we aim to create an environment where innovation can accelerate while preserving the reliability, compatibility, security, and operational excellence that organizations around the world depend on.”

Q1. Oracle has announced a “new era” of MySQL community engagement at MySQL’s 30th anniversary. Can you walk us through what specifically prompted this strategic shift, and what concrete changes can the community expect to see in how Oracle approaches MySQL development and governance?

HVC: Throughout 2025 we celebrated 30 years of MySQL and reflected on the past and present, but more importantly, the future. The MySQL Community team sought feedback from around the globe on how to lead the next generation of MySQL innovation and open source collaboration. We came to Jason …

MySQL has dropped its newest release , categorized as “Early Access” and available at https://labs.mysql.com/ . While this post is not going to go into depth, I wanted to at least validate the management changes you verify between normal MySQL upgrades.

With the release of MySQL 9.7 Community Edition, the Hypergraph Optimizer is now available to everyone. This is a significant addition to MySQL and one that has generated a lot of excitement in the MySQL community. The promise is simple: better execution plans for complex queries, especially those with many joins. Like most new features, […]

Modern applications are expected to deliver instant responses while processing increasingly large volumes of data. Achieving this level of performance isn’t simply a matter of making the database faster.It requires placing the right workload on the right layer of the architecture. Some operations require ultra-fast repeated reads, others demand transactional consistency, while analytical queries benefit […]

The post OCI Cache and MySQL HeatWave: Better Together for High-Performance Applications first appeared on Data Daz (dasini.net) - Data Systems, AI, and Real-World Insights.

MySQL is one of the databases developers trust most when an application needs a proven, familiar, open source relational engine. Kubernetes has become the orchestration layer teams rely on to run and scale modern workloads. Put them together, and the question gets interesting: how do you run MySQL with the same declarative, repeatable operating model […]

Over the past year, we have taken important steps to increase transparency and engagement across the MySQL ecosystem. Through public roadmap discussions, Early Access releases, publication of worklogs, bug transparency and backlog reduction, community public discussions, increased use of GitHub discussions, and contributor events, we have created more opportunities for the community to understand what […]
