Vibe-coding an Audit Plugin in Under 3 Minutes
Who says developing MariaDB plugins is hard? I was able to produce one in under 3 minutes!
I of course did it by asking Grok nicely:
The produced result is actually very decent:
It even produced a Makefile:
And compilation instructions:
The plugin has even compiled and worked on my Mac!
Tests are Important!
While I had Grok’s attention I’ve given it a follow up task:
Note the “please” part! It’s important!
This second prompt made it realize its naiveté […]

Unleashing Innovation Through Plugins
One of the corner stones in MariaDB Foundation’s mission is:
We strive to increase adoption by users and across use cases, platforms and means of deployment. https://mariadb.org/about/
MariaDB Server plugins are definitely a prime “means of deployment” for server features. But a relatively neglected one so far. They have been around for many years. But, somehow, they have escaped the user’s focus. Why that happened is a very interesting topic. And one that I’d definitely like to hear your opinion […]

Adding a New Data Type to MariaDB with Type_handler – Part 5
We are concluding our series related to new data types using the Type_handler framework, with some limitations that are not yet covered by the framework:
It would have been handy for our MONEY datatype to have the possibility to define, for example, the currency to show. Or the format to have something like this:
Unfortunately, we can’t create new field attributes for our data type. As you probably already know, a column has an extra attribute called COMMENT. We can […]

Adding a New Data Type to MariaDB with Type_handler – Part 4
This is part 4 of a series related to extending MariaDB with a custom data type using the Type_handler framework.
You can find the previous articles below:
Overriding Existing Types
In the previous examples, our MONEY data type inherits from DOUBLE and then we override some methods.
But all the methods of every type cannot be overridden. For example, if we would like to change how the money column is sorted, we would have to override the Field_double::sort_string() method. But […]

Adding a New Data Type to MariaDB with Type_handler – Part 3
In the previous article, we wrote, compiled, and tested our first custom data type for MariaDB using the Type_handler framework.
But currently, aside from allowing the use of its new name (MONEY) and listing it in the metadata, our new data type behaves exactly like a DOUBLE, the class it inherits from.
In this article, we will extend our data type just a bit by transforming the result into a VARCHAR and adding a currency sign to it: the dollar […]

Adding a New Data Type to MariaDB with Type_handler – Part 2
After having discovered the Type_hander framework and learned how to build MariaDB Server from source, it’s time to code our first data type!
We will create a MariaDB plugin that registers a new MONEY type and instantiates a custom field object.
Our component won’t be exciting, but we want to understand how to use the framework and test it.
We want to prove that
Everything else comes later.
Step 1: start with a minimal build file
The very first step […]

Adding a New Data Type to MariaDB with Type_handler – Part 0
Welcome to this new series about extending MariaDB. This series covers the addition of a new data type using the Type_handler.
The goal of the entire series is to create a new plugin data type MONEY to store and display amounts with currency.
Something like:
Of course, the ultimate goal is to teach how to add data types in MariaDB, and we expect to see how creative our community developers are!
This is Part 0 – Build MariaDB from the […]

10.7 preview feature: Password Reuse Check plugin
By default, MariaDB does not check if a user reuses a password. Some security policies require users to choose a new password each time, and the Password Reuse Check plugin, available in a MariaDB 10.7.0 preview, enables this functionality.
Old passwords are stored in the mysql.password_reuse_check_history table, and the period they are retained for is determined by the password-reuse-check-interval system variable, which specifies a number of days. By default this is zero, meaning unlimited retention.
The password can be used […]
