A MySQL InnoDB Cluster provides high availability for a single database cluster using Group Replication. This works well for node failures inside the cluster, but disaster recovery usually requires another cluster in a separate location: another Kubernetes cluster, region, data center, or cloud….

Upstream MySQL published an out-of-schedule release this week with two high-severity CVE fixes. If you’re running Percona Server for MySQL 5.7 or 8.0 under Extended Lifecycle Support (ELS), the program we previously called Post EOL Support, you don’t have to do anything to qualify for them. We’ve already applied the fixes and re-released the affected … Continued The post Still on MySQL 5.7 or 8.0? Those high-severity CVE fixes are covered appeared first on Percona…. Read more

PostgreSQL Autovacuum Internals and Benchmark Introduction Vacuum, or more precisely autovacuum, is the most important automatic maintenance task in PostgreSQL. It is key for performance, but also for long-term database survival. If it runs too often, it can damage performance. If it does not run often enough, performance can suffer. With too few workers, it takes too long. With too many, it consumes resources. If the maintenance work memory is not enough, the load can multiply due to multiple index scans. If you disable it completely, it will rise from the dead and run without limits…. Read more

Historically, relational databases did double duty. The same PostgreSQL / MySQL instance that handled your application’s writes also answered your business questions. A well-indexed schema, a few GROUP BY reports, done. And that works, right up until it doesn’t: the reports get slower, the dashboards start eating the same I/O budget as the application; or, […] The post Building a Modern Analytics Stack Around ClickHouse appeared first on Severalnines….

PostgreSQL community images address a real gap in how a Kubernetes database operator earns your trust. Running a database operator on Kubernetes means trusting two things: the code, and the container images the operator pulls. The code is on GitHub, easy to inspect, easy to fork. The container images, the registry that hosts them, and the … Continued The post Community Docker Images: keeping the operator open without a vendor registry lock-in appeared first on Percona….

Debugging applications in Kubernetes can be tricky. Containers are designed to be small, immutable, and purpose-built. That is great for production, but not always ideal when something breaks. Many production images are minimal or distroless. They may not include tools that are useful for troubleshooting. In some cases, the application container may already be crashing, … Continued The post Debugging with Ephemeral Containers appeared first on Percona…. Read more

A few years ago, if there was a discussion on “Should we run databases on Kubernetes?”, there were more people saying no than yes. One of the common answers was, “No. Kubernetes is for stateless workloads. Keep your databases outside.” Thankfully, today the discussion is no longer about whether we should run databases on Kubernetes, … Continued The post Why I haven’t run my databases on Kubernetes appeared first on Percona….

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….

We’ve pulled those fixes into our next builds and are skipping the two versions we had already queued: Percona Server for MySQL 8.4.9 and 9.7.0. These fixes arrived through Oracle’s new monthly Critical Security Patch Updates (CSPUs), which Oracle announced begin May … Continued The post Skipping Percona Server for MySQL 8.4.9 and 9.7.0 appeared first on Percona….
