A Practical Guide for MySQL HeatWave Capacity Planning
As organizations modernize their data platforms, MySQL HeatWave has emerged as a powerful solution for running online transactional processing (OLTP) and real-time online analytics processing (OLAP) together without ETL complexity. However, achieving optimal performance and cost efficiency requires thoughtful capacity planning. This blog explains how to monitor and estimate MySQL HeatWave capacity using SQL queries, […]
Designing Resilient APIs with MySQL HeatWave High Availability and Read Replicas
Modern cloud applications are expected to remain available even during infrastructure interruptions, replication failovers, maintenance events, and transient network failures. In distributed database environments, it requires applications to treat transient failures as a normal part of production operations. This blog discusses practical API reliability designs for applications using MySQL HeatWave High Availability and Read Replicas, […]
Backrest's back, alright!
Events unfolded quickly over the course of a couple of weeks starting on 27 April 2026, when a message appeared on the pgBackRest project announcing: that the repository would be archived and active maintenance would stop.
Building an AI Vision Search Engine with MySQL HeatWave GenAI
Modern AI systems increasingly rely on multimodal data: text, images, documents, audio, and video. Among these modalities, image understanding has become one of the most important capabilities for AI-powered applications.
Traditionally, implementing these capabilities required specialized computer vision infrastructure, external vector databases, custom ML pipelines, and multiple frameworks.
With MySQL HeatWave GenAI, many of these capabilities can now be implemented directly inside SQL workflows using built-in AI routines.
In this article, we will build the foundations of a…
Two projects, one mission - hackorum and pginbox join forces
Last week, Zsolt and I jumped on a call with someone who had been building something remarkably similar to what we had been working on, completely independently. That someone is Jack Bonatakis, the creator of pginbox.dev, and that call turned into one of the most energizing conversations we’ve had since launching hackorum.dev.

Meet the Percona Community team
We’ve just landed on X and Mastodon, and before the first real post goes out, we wanted to do something we don’t do often enough: introduce ourselves.
A New Era of MySQL Monitoring: OpenTelemetry Metrics with Prometheus
In modern application development, observability is no longer optional. It is a core requirement for stable operations, faster troubleshooting, and better understanding of system behavior. Databases are especially important because they often sit at the center of application performance. When a database becomes slow, overloaded, or unavailable, the impact is usually felt across the entire […]
