MySQL Best Practice : not using date / time types, nor ENUM

Today, I was reminded of a MySQL Best Practice, probably generalizable to all databases : using simple types, not complex types.  Such complex types to avoid include the date and time data types (including TIMESTAMP) and ENUM.  Let's see why.

A little history about this, Baron Schwartz, a MySQL Legend who is not involved in the community anymore, compared using the TIMESTAMP type to

Why are databases so hard?

You've probably all experienced it; another outage and the database is the root cause.  Why are databases such a frequent cause of problems in most tech stacks? Why can't we seem to solve these problems industry-wide?  Are database engineers and database admins just bad at their jobs?

Over my career as a database reliability engineer, I've come to a conclusion which I don't see repeated often:

All practical implementations have to balance the opposing concerns of correctness vs. performance & availability (this is kind of similar to CAP theorem , but not exactly the same).   Perfect correctness with no data loss across geographic distances would result in a database which is too slow or too costly to be useful for most applications. And these constraints cannot be overcome because it's the physical bounds of reality which imposes …

When Tungsten Replication "Stalls" but Nothing Has Failed: A MySQL Metadata-Query Story

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.

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 […]

A New Era for MySQL: Heather VanCura and Jason Wilcox on Open Source, Community Governance, and Where MySQL Is Headed

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 …

A first look at MySQL 26.7 Early Access

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.

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 […]

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 on OKE: Database Operations as Kubernetes State

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 […]

From Tokyo to Seoul to Taipei: MySQL Community Conversations Across JAPAC
