MariaDB Foundation is delighted to welcome Seravo as a Silver Sponsor, turning a long-standing relationship in the open-source ecosystem into formal support for the future of MariaDB.
Seravo is a Finland-based specialist in premium hosting and upkeep for WordPress and WooCommerce. Open source sits at the heart of its technology stack and its company culture, and MariaDB has been part of that story for many years.
MariaDB behind the WordPress ecosystem
For hosting providers, databases are not an abstract technology choice. They sit underneath millions of page loads, online transactions, content updates and applications that people depend on every day.

MariaDB already allows developers to add new Pluggable Data Types and scalar Plugin Functions. One missing piece has been Pluggable Aggregate Functions operating on PDTs. That matters for functionality such as HyperLogLog, where an extension needs to aggregate values into a custom statistical sketch while preserving its native SQL type.
MDEV-40672 closes that architectural gap. Aggregate functions can now participate in MariaDB’s native aggregation infrastructure, including DISTINCT, window execution, prepared statements and Pluggable Data Types.
MariaDB already supports MariaDB_FUNCTION_PLUGIN, a mechanism for registering SQL functions that create regular server Item objects and can behave almost like built-in functions.

Overview
While validating MariaDB RSS stability under stored procedure workloads, I ran into unexpected memory growth. The goal was straightforward: confirm that MariaDB was not leaking memory when running TPROC-C stored procedure workloads. To do this, I used HammerDB TPROC-C SP and added improved RSS monitoring so I could watch memory usage over long-duration runs.
The results were clear. MariaDB RSS stayed stable. HammerDB 5.0 kept growing, and growing.
This led to a deeper investigation into HammerDB itself, and ultimately to an update in TAF to support HammerDB 6.0 and a new RSS logging script.

JSON support in MariaDB has improved significantly over the years.
We have functions to create JSON documents, extract values, modify objects, inspect arrays, compare documents, and even transform JSON into relational rows using JSON_TABLE().
But sometimes, a very small piece of syntax can make a surprisingly large difference.
With MariaDB 13.1, we can finally write:
document->’$.customer.name’
and:
document->>’$.customer.name’
Yes, the JSON arrow operators have arrived in MariaDB!!
And MariaDB 13.1 also improves JSON_TABLE() with support for formatted JSON columns, allowing complete JSON objects and arrays to be returned without converting them into scalar SQL values.
…

Auree is building a cloud-independent platform for deploying and operating highly available open source databases, including MariaDB, inside customers’ own cloud accounts. Its Bring Your Own Cloud model allows organisations to choose their cloud provider, region, infrastructure size, and security environment while Auree automates database provisioning, monitoring, backups, clustering, and failover.
This approach addresses a growing concern among organisations adopting managed database services: how to gain the operational benefits of the cloud without surrendering control of their data, infrastructure, or future deployment choices.
Auree’s platform uses a lightweight 2+1 architecture, consisting of two database nodes and a smaller witness node responsible for quorum.

Be it known: MariaDB Server now has a clearer, publicly documented governance framework covering technical roles, subsystem ownership, decision-making, response expectations and continuity.
Open source begins with access to the code. Yet for infrastructure expected to remain dependable for many years, openness must also extend to how responsibility is assigned, how decisions are made, and what happens when people disagree or move on.
The framework formalises much of how the project has long worked, while making its responsibilities, decision paths and commitments clearer and easier to inspect.
The central principle is simple: authority should be visible, earned and connected to responsibility.
