In this blog post the MySQL Operator for Kubernetes will be explored by using the operator Helm charts. Scenarios of simple Operator installation and creation of MySQL InnoDBClusters will be shown. Advanced topics, like usage of air-gapped container registry will also be presented.

Cluster/J is Oracle’s NoSQL Java development environment for MySQL NDB Cluster. When it was originally released 15 years ago, Cluster/J aimed to couple state-of-the-art Java enterprise application architecture with a high-performance direct interface to NDB data. Today it is used in video streaming, in telco applications, and in an Open Source feature store infrastructure that powers some of […]

Security is a foundational principle for cloud deployments, especially when dealing with mission-critical workloads like those managed by HeatWave MySQL. As applications and environments scale, fine-grained network control becomes critical not just for protecting sensitive data, but also for isolating systems, enforcing boundaries, and minimizing lateral movement within a Virtual Cloud Network (VCN).

TL;DR Percona Server for MySQL now offers experimental support for stored programs in the JS language. This free and open source alternative to Oracle’s Enterprise/Cloud-only feature enables users to write stored programs in a more modern, convenient, and often more familiar language. It is still in active development, and we would very much like your […]

MySQL Server utilizes keyring to store cryptographic keys used by several modules to secure data stored by them. For example, InnoDB storage engine uses a key to encrypt tablespace, binary log and relay log management use keys to encrypt passwords for the log files. There are several keyring components and plugins that may be used […]

I recently troubleshoot an interesting MySQL crash, and I think it is worth sharing (with the related bugs).  MySQL crashed when the disk was full, you can see the free disk graph below.  The Y-axis is in the tens of GiB scale and the X-axis is in the hour scale.  Can you guess what happened ?

Just to make sure we agree on the meaning of the graph above, let's describe it
