The Galera Crossroads: Why PXC is the Lifeline for MariaDB Community Users
Or: Surviving the Codership Acquisition Without Losing Your Cluster
Why this long post?
Recently, the database landscape shifted significantly when MariaDB plc absorbed Codership. If you aren't familiar, Codership is the company that introduced the Galera library and the WSREP API to MySQL, creating the first virtually synchronous replication solution for the MySQL ecosystem. For years, they produced their own highly stable, patched version of MySQL + Galera, which was widely adopted alongside solutions like Percona XtraDB Cluster (PXC).

Building Smart Semantic Search using PostgreSQL and pgvector. Part 3 - Hybrid Search, Percona Blog, and Widget Improvements
Here I write about what I changed after the first launch: hybrid search, filters and counts on the search page, the widget layout, indexer hardening, and the Percona Blog in the index. People often type short words or names, and pure vector search is weak at that. When I turned search on about a month ago I asked for feedback in Part 1, and most of what follows came from that.

Why PostgreSQL needs an AI usage policy
We often hear that open source is about people.
From JSON by Hand to a Guided MySQL Enterprise Edition Audit Filter Wizard
MySQL Enterprise Edition includes powerful audit filtering capabilities, but writing audit filter JSON by hand can be tedious and error-prone. The JSON model is flexible, which is exactly what makes it useful, but it also means that a small typo, a missing event class, or an incorrectly assigned user can change what does or does […]
The Next Phase of MySQL Community Engagement: Accelerating Participation and Collaboration
For over 30 years, MySQL has grown through the contributions, feedback, and collaboration of a global community of developers, database administrators, customers, partners, educators, and open source advocates. That community has helped make MySQL one of the world’s most widely used open source databases. As the ecosystem continues to grow and evolve, so do the opportunities for collaboration. Over the past year, we have […]
Create Replica DB system Made Easy for MySQL HeatWave Service on OCI
MySQL HeatWave Service (MHS) on Oracle Cloud Infrastructure (OCI) already provides multiple ways to create a new DB system, such as restoring from a backup, using Point-in-Time Recovery (PITR), or importing data from Object Storage. However, when creating a new DB system from an existing DB system, especially in another region, the process required several sequential […]
Do not uselessly grant CREATE and ALTER TABLE
This lesson should have been learned with the CREATE TABLE of death, but it is worth a refresh.
Do not uselessly grant CREATE and ALTER TABLE
The reason I am posting this reminder is that another crashing bug related to DDL came to my attention. This bug is only fixed in a recent version of MySQL (probably not affecting 5.6 and 5.7), so if you are running the latest 8.0 or 8.4, you should
