Post-Quantum Cryptography support in MySQL
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 […]
Introducing 🍃MClusterAdmin: A Lightweight GUI Tool for MongoDB DBAs
Over the years working on various MongoDB troubleshooting cases, I’ve been wondering how to handle the longish JSON outputs from the most common diagnostic commands, like rs.status(), sh.status(), or db.currentOp(), not to mention db.serverStatus()! They are just painful and slow to read. I even came up with various scripts to present the data in table format, similar to what we know from MySQL, but I was never satisfied with them.
MySQL 9.7 Community Edition: Smarter Join Planning with the Hypergraph Optimizer
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, […]
OCI Cache and MySQL HeatWave: Better Together for High-Performance Applications
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 […]

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 […]
TDE performance in PostgreSQL
What’s the impact of TDE on performance? People usually quickly throw together a few graphs with basic measurements and treat that as a complete answer, but the question is a bit more complex than that. In this blog post, I’ll try to explain it in a bit more detail: why showcasing a single graph isn’t good for anything other than marketing.
From Tokyo to Seoul to Taipei: MySQL Community Conversations Across JAPAC
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 […]
Perconians at WeAreDevelopers World Congress 2026: Agents Everywhere, Security Wake-Up Calls, and Buzzword Bingo
On July 9–10, the two of us - Sandra (Engineering, Percona for MongoDB) and Radek (Product, Percona for MongoDB) - packed our backpacks and headed to Berlin for the WeAreDevelopers World Congress Europe 2026 (WAD). The 11th edition of the congress gathered 15,000 developers and 500+ speakers for two intense days, and we came back with full notebooks, fresh ideas, and one very clear message from the industry.
Introducing Mountaineers: A Way to Say Thank You
You filed a bug report at 11pm because you’d already done the work to isolate it. You answered a forum question that had been sitting unanswered for three days. You wrote a PR. You spent an hour on a call telling us what’s broken about a tool you use every day. None of that is small, and none of it should go unnoticed.
