Planet MySQL HA Blog

As MySQL HeatWave environments continue to grow, many organizations prioritize scaling compute and storage resources while overlooking a critical area: database housekeeping. Inadequate maintenance practices can result in excessive storage consumption, longer backup and recovery times, replication lag, degraded query performance, and increased operational costs. This blog highlights key database hygiene and optimization strategies for […]

You’ve fixed something gnarly in production this year. You’ve migrated a database that nobody wanted to touch. You’ve built something on top of Percona Operators, or Percona Toolkit, or Percona Monitoring and Management (PMM), and you’ve learned things along the way that aren’t written down anywhere yet.

Organizations modernizing transactional database environments are increasingly adopting MySQL HeatWave to simplify operations, improve scalability, increase availability, enhance security and enable real-time analytics without separating OLTP and OLAP systems. However, successful adoption requires more than simply provisioning a new database instance. This blog explores practical best practices for provisioning and migrating OLTP and OLAP workloads […]

PostgreSQL has become a favorite database for modern application teams: open source, extensible, standards-friendly, and proven across transactional, analytical, geospatial, SaaS, and cloud-native workloads. But as PostgreSQL estates grow, so does the operational burden: patching, backups, monitoring, scaling, storage planning, replication, failover, disaster recovery, security hardening, and version upgrades. That is where OCI Database with […]

In December, we introduced how Model Context Protocol could make ClusterControl easier to work with from AI assistants. Since then, Severalnines has expanded that MCP direction across its database operations platforms with ClusterControl MCP and CCX MCP. The latest ClusterControl MCP is the major update, providing a more robust implementation with 69 tools and 20 […]

The post AI-Assisted Production Database Ops with ClusterControl MCP and CCX MCP appeared first on Severalnines.

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, […]

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, […]

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.

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…

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.
