Deep dive into Clang sanitizer testing with MariaDB
MariaDB uses Clang’s memory, address, and undefined behavior sanitizers are used for identify coding flaws during the continuous development and testing process. MariaDB would like to share via an online event on how easy perform the same sanitizer checking.
The MemorySanitizer environment is particularly onerous to create. Because MariaDB use container based build and testing, we have an environment that can be re-used by anyone.
Our “Deep Dives” were once an internal skills transfer mechanism, however for the first time […]

Tell us how to DROP USER!
Shortly, we will start coding a task, for which we would appreciate your input: How would you like to DROP USER?

So now we’re considering changing it.

Innovation involves applications using MariaDB Vector, like RAG, and integration being enabling MariaDB Vector in an existing framework.
Participants range from individual contributors to even a corporate team. […]

Always use the right UUID in MariaDB
The following post was written by Stefano Petrilli, who contributed UUIDv4 and UUIDv7 implementations to MariaDB. Thank you, Stefano!
The original version of the Universal Unique IDentifiers (UUID), which is now known as UUIDv1, made his first appearance in the 1980s. The most interesting guarantee that they provide is the generation of IDs that are always unique across space and time.
To comply with this promise, it uses a combination of three elements:
Plus, it sets 6 bits to a […]
