Welcome

Ronald Bradford has spent 30 years building large-scale data systems, with deep specialization in MySQL and the open source relational database ecosystem. His work spans the full lifecycle of data — designing resilient, scalable architectures, shaping the data strategy that guides how organizations store and use information, and hardening that data against an evolving security landscape.

He approaches data architecture as both an engineering and a strategic discipline: not only how systems are built to scale and recover, but how data decisions align with long-term organizational goals. That perspective draws on decades of hands-on performance engineering, replication and high-availability design, and database security practices — increasingly relevant as AI workloads place new demands on data integrity, governance, and access control.

A long-standing contributor to the open source database community, Ronald is the author of the Effective MySQL book series, a recognized MySQL Subject Matter Expert, and Oracle ACE Director Alumnus. He contributes to the VillageSQL community extensions for MySQL and has presented at conferences in 23 countries. His current work explores the intersection of databases and emerging AI — including running generative AI directly against database systems and the security implications that come with it.

Fixing Old Software Bugs Without Thinking

I previously came across an issue in my benchmarking work where I relied on the Latency Histogram section of sysbench output. On Linux it worked fine — I generally ran my workload there, so it never mattered.

Curating DuckDB Datasets Leveraging AI

In Curated MySQL Data Sets for Realistic Testing I described datasets assembled the manual way — download, schema, load, validate, document — over hours or days per source. This post is the follow-up I promised: what changes when AI assists the same workflow, using DuckDB as the target engine and GeoNames as the first example.

Why INSERT IGNORE should not be used

Let’s say you’re building a reference table from source data, e.g. a silver medallion table from a primary source. In this example I am using a file of random locations on the globe extracted from OpenStreetMap (OSM) as my primary source.
