Building Smart Semantic Search using PostgreSQL and pgvector. Case Study - Part 1
Type “zero downtime database migration” into the site’s search bar and you’ll get articles and talks about database migration with minimal downtime, even if those words aren’t in the titles or content. This is semantic search on PostgreSQL and pgvector, without paid embedding APIs or a separate vector database. In this series I’ll cover how it works and why I chose this stack.
MySQL HeatWave Document Store for Modern Applications
Modern applications generate and consume enormous amounts of semi-structured data. User profiles, product catalogs, IoT telemetry, application events, AI prompts, and content metadata rarely fit neatly into rigid relational schemas anymore. At the same time, enterprises still need the reliability, security, analytics, and operational maturity of a traditional database platform. This is where MySQL HeatWave […]
MySQL HeatWave Database Housekeeping Best Practices
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 […]
Write for the Percona Community
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.
Best Practices for MySQL HeatWave Adoption for OLTP and OLAP Workloads
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 […]
Why Move PostgreSQL to Oracle Cloud Infrastructure? A Deep Dive into OCI Database with PostgreSQL
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 […]
AI-Assisted Production Database Ops with ClusterControl MCP and CCX MCP
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.
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.
