Planet MariaDB Server

When I started learning tennis as an adult, I realized that what made tennis difficult was not learning the tennis strokes, instead it was learning to realize the value of the feedback loop: racket vibrations, tennis ball sounds, and the way my balance shifted before I even realized it. None of this information is obvious on the court. However, without it I would continue to make the same significant error, and be frustrated that “trying harder” doesn’t seem to aid.Read more

Starting with Percona XtraDB Cluster (PXC) 8.0, replication traffic encryption is enabled by default. That said, it’s common to find clusters running without TLS that suddenly need it: a new compliance requirement, an audit finding, a network segment that is no longer considered trusted. PXC has a variable for exactly that case, pxc-encrypt-cluster-traffic, which handles … Continued The post Enabling TLS in PXC without Downtime appeared first on Percona.Read more

Percona Operator for PostgreSQL 3.1.0 takes on three things that decide whether a PostgreSQL platform passes review: is the data encrypted at rest, can it serve reads without straining the primary, and are the logs there when you need them. This release answers all three inside the custom resource, so none of them is a … Continued The post Percona Operator for PostgreSQL 3.1.0: Transparent Data Encryption, Logical Replicas, and Persistent Logging appeared first on Percona.Read more

“Expensive queries” is a phrase that hides two different problems. One is response time: a statement the application waits too long for. The other is resource efficiency: a statement that burns CPU, logical reads and […]Read more

A database migration can be syntactically correct and still be a poor release candidate. A regular index build can block writes, an ALTER TABLE may wait behind a conflicting lock or hold a strong lock longer than expected, and a large data modification can turn a routine deployment into an incident.Read more

When setting up a new database for an application, high availability (HA) is one of the main priorities. Let’s assume for this example that you chose to use a Percona XtraDB (PXC) cluster to host your database. But how does the application know which PXC node is healthy and can receive application traffic? Introducing a cluster of ProxySQLs can solve this problem, as ProxySQL will healthcheck the database nodes and route the application traffic to the healthy nodes. However, now the HA problem comes up again: how does the application know which ProxySQL host is healthy?Read more

This is the MinervaDB Data Migration Team’s write-up of an Oracle Exadata to PostgreSQL 18 migration for an airline operations platform: crew scheduling, flight status, aircraft rotation and the reporting that hangs off them. The […]Read more

Your transactional database is not failing you. It is doing precisely what it was engineered to do: take a write, make it durable, isolate it from every other write, and never lie about it. The […]Read more

A few weeks ago, we asked a simple question: Which language would you use to write MariaDB plugins? The question related to MDEV-40189 (Support plugins written in various languages), an idea we introduced earlier this summer to lower the barrier to MariaDB plugin development by supporting languages other than C and C++. … Continue reading “MariaDB Plugins Beyond C++: What the Community Told Us” MariaDB Plugins Beyond C++: What the Community Told Us appeared first on MariaDB.orgRead more
