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.

MariaDB Contribution Statistics, June 2023

We are well into 2023 now, the time has really flown. There have already been two major versions of MariaDB Server that have reach GA, and with those, many new contributions. As with each quarterly metrics release, the raw data is available in our metrics repo, along with the scripts and configurations to generate it yourself.

Project Tracking

We are tracking multiple MariaDB related projects at the moment, many of which are pulled in when you build MariaDB Server. These include:

  • MariaDB Server – the server itself
  • libmarias3 – an open source library to talk to Amazon S3 and related block storage services.

MariaDB Contribution Statistics, March 2023

Due to a catalogue of issues our previous quarterly update for developer metrics was not published. This time, however, we have made quite a few changes. In this post, we will summarise 2022 and what has happened in the first couple of months of 2023. All the data for this blog post can be found in CSV format in the release section of the MariaDB Metrics repository, along with everything you need to generate the metrics yourself.

Changes to metrics gathering

For the main commit metrics, we use a tool called “GitDM” or Git Data Miner which was developed for the git kernel trees to group commits by people and organisations.
