The increase of cloud-native technologies is transforming how we manage databases. Since I stepped into the world of databases and cloud-native technologies, I have encountered several initiatives aimed at developing and optimizing database operations in the cloud, and Kubernetes plays a crucial role in this shift through Operators. While the core concepts and techniques of […]

If you’re managing a PostgreSQL database and handling sensitive data or PII, the answer is simple: You need data-at-rest encryption. This isn’t just a “nice-to-have” feature—it’s often a legal or regulatory requirement. Compliance auditors, security officers, and privacy-conscious customers all expect it.  But is this enough?  We think NO! The reality check: No native TDE […]

Over the last few years, there have been many calls to evolve the Open Source Definition (OSD) to fit the modern world. Some would like to see noncompetitive licenses such as the Server Side Public License (SSPL) or Elastic License considered open source. Others approach this by thinking about ethics and “using software for good and […]

Recently I listened to Lenny Rachitsky’s podcast, where he invited Shreyas Doshi for the second time. The session was titled “4 questions Shreyas Doshi wishes he’d asked himself sooner”. One of the questions Shreyas brought up was, “Do I actually have a good taste?”. This is an interesting question to ask for an experienced product […]

PostgreSQL 12 reached its End of Life (EOL) on November 14, 2024. For more information, see the official PostgreSQL versioning policy page. This milestone marks the end of regular updates, bug fixes, and critical security patches for version 12. If you are still running PostgreSQL 12 in your production environment, it’s time to start planning […]

Originally published on The New Stack. Building a flexible cloud strategy means making decisions that align with operational efficiency, cost management, and scalability. Public cloud platforms offer immense convenience but come with certain downsides. High long-term costs, vendor lock-in, and lack of flexibility are concerns for many organizations. As businesses grow, the allure of quick-starting […]

Managing keys inside Valkey/Redis is crucial, especially when we need to test in a different environment or restore a partial/specific key-value dataset for a migration or production movement event. Although we can use a full RDB snapshot + AOF to get the full data set, that is not always feasible if we focus on a […]

When I talk to old-timers in the MySQL community, I often hear this question: “How come MySQL is so awesome and still more popular than PostgreSQL (according to DB-Engines methodology at least), but it is losing ground while PostgreSQL’s growth in popularity has been unstoppable?” Can anything be done in the MySQL ecosystem to reverse […]

Migrating from Redis to Valkey can significantly reduce costs associated with private licensing for your application. However, the biggest concern in any migration is transitioning without disrupting service or causing downtime. In this blog post, we’ll guide you through a step-by-step approach to smoothly migrate from Redis to Valkey without interrupting your application’s operations, providing […]

Inspired by this comment in the Hacker News discussion, I posted polls on my LinkedIn network about the tendency (or perception of tendency) to abandon features without deprecating them in some of the most popular open source databases – MySQL, MariaDB, and PostgreSQL.  First, let’s look at why “Abandoning” features rather than formally depreciating them […]
