From a Chocolate Wrapper to Concurrent InnoDB Page Splits
This work started from a conversation with Monty Widenius at Meet Magento Czech in August. We discussed possible ways to improve the scalability of the InnoDB B+Tree, especially its insert path and page splits.
Monty explained several ideas about reducing synchronization during structural changes and allowing independent parts of the tree to make progress concurrently. We did not have a whiteboard, so we made the first design sketch on the back of a dark chocolate wrapper.
The sketch contained a […]

Extending MariaDB with Native Aggregate Plugins: Laying the Groundwork for HyperLogLog
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 […]

MariaDB Foundation Advances TAF with HammerDB 6.0 and xt_reservoir Integration
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 […]

Hear Ye, Hear Ye: A Guide to MariaDB’s Governance Model
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 […]

Say the Name: MariaDB, MySQL, and the Ecosystem We Share
MariaDB and MySQL share history, tools, protocols and a large technical community. But compatibility does not mean identity—especially when reporting bugs. A MariaDB Connector/C issue submitted to the MySQL bug tracker offers a funny reminder to say the product’s actual name.
