The Queen’s Gambit: Through the Looking Glass into the Query Optimizer

There’s a question I like to ask people sometimes—especially at turning points:

What’s your word?

One word to capture how you feel, where you are, or what’s driving you right now. No explanations. Just instinct.

Today, mine is: Adventure.

Not necessarily the reckless kind, but the kind that stretches you—where you step into something unfamiliar and see what happens. That’s exactly what this season at MariaDB is like. 

And maybe the most “adventurous” thing I’ve done so far? Emailing Andy Pavlo.

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:

  • The node, which is a field that identifies the machine that generated the UUID.

The Accidental Queen of the Database Dominion – Month one

Exactly one month ago, I found myself stepping into the role of CEO at MariaDB Foundation. It was a bit like being handed the keys to a beloved old ship and being told, “Don’t worry, it mostly steers itself… unless there’s a storm. Or a kraken. Or a GitHub issue.”

As someone whose surname gives away a bit of context, it’s both an honor and a deeply personal journey to be entrusted with stewarding this next chapter. I used to say that I have done my bit for the project by adding “Maria” to “MariaDB”, but what do you know it turns out – there is a lot more out there for me to do!!!
