When people ask me how to tune MySQL, they usually mean, “Which variables should I change in my.cnf?” (the MySQL configuration file) That certainly is a reasonable place to start, because most day-to-day performance tuning really is driven by MySQL itself: memory allocation, redo flushing, connection handling, temporary tables, and InnoDB I/O behavior. But the […]

As an update to our recent blog post, “Where can you find MySQL next? (Updated events list for March–May 2026)” we’d like to share the latest confirmed MySQL events and webinars, including newly added ones plus refreshed details for sessions we already announced. Since plans and agendas evolve quickly, this post is intended to provide […]

As part of our MySQL community engagement plan, which includes delivering new features into MySQL Community Edition, increasing collaboration and transparency, and expanding and growing the MySQL Ecosystem, we have created a new rhythm of public MySQL Community Discussions—starting with our first session on February 25 and continuing with our second session on March 23, […]

Production data is invaluable for day-to-day operations—support, troubleshooting, analytics, and development. But when that data contains sensitive fields such as SSNs, emails, phone numbers, or other identifiers, broad read access can quickly become unnecessary exposure.  Just as importantly, many organizations operate under regulatory and contractual requirements that expect strong controls around access to sensitive data—often including data masking as […]

MySQL is extending caching_sha2_password to support PBKDF2 with SHA-512 as a new password storage format. This is a meaningful step forward for password security because it strengthens stored password transformations without requiring a new authentication plugin, without breaking clients, and without forcing an all-at-once migration. Existing accounts continue to work, new passwords can use the stronger format, and administrators […]

Overview Some MySQL distribution packages, such as the generic Linux build, bundle an OpenSSL dependency within the same .tar.gz archive. With the new MySQL 8.0.46, 8.4.9 and 9.7.0 releases, we are upgrading those bundled packages from using OpenSSL 3.0 to the new OpenSSL 3.5 LTS branch. Native OS packages, such as .rpm and .deb, continue […]

The following report is covering performance evaluation of the currently available OpenSSL releases when they are used by MySQL in CPU-intensive OLTP workloads. However, the main focus is on OpenSSL-3.5.5, which will be used by default in the next MySQL releases.

With MySQL 9.7.0 LTS, MySQL establishes its next long-term support release line, expands key capabilities in Community Edition, and introduces Dynamic Data Masking for Enterprise users. The April releases mark an important milestone for MySQL. With the GA of MySQL 9.7.0 LTS, MySQL moves from the 9.x innovation series to a new Long-Term Support release line. This begins […]

Having a separate DR cluster for production databases is a modern day requirement or necessity for tech and other related businesses that rely heavily on their database systems. Setting up such a [DC -> DR] topology for Percona XtraDB Cluster (PXC), which is a virtually- synchronous cluster, can be a bit challenging in a complex Kubernetes environment.

Here, Percona Operator for MySQL comes in handy, with a minimal number of steps to configure such a topology, which ensures a remote side backup or a disaster recovery solution.

So without taking much time, let’s see how the overall setup and configurations look from a practical standpoint.

PXC Cross-Site/Disaster Recovery

DC Configuration
