MariaDB Contribution Statistics, January 2024

It is the start of a new year, and with that brings the start of a new quarter, which means it is time for a contribution statistics update from us. I have lots of interesting data to walk you through this time, so let’s get started.

Year On Year Comparison

A good place to start would be to compare the previous year gone by with last year to see how we did. This table shows the number of organisations, contributors and commits to MariaDB Server in the last few years. The “Non-MariaDB” lines are contributors and commits by people who are not employed by MariaDB Plc or MariaDB Foundation.

MariaDB Server will be the default database in cPanel

Good news! cPanel, one of the leading control panels in the hosting world has just announced that they are going to make MariaDB Server the default database when installing new cPanel instances. This change is slated to occur in version 122 of cPanel & WHM, coming in Q3 of 2024. We at MariaDB Foundation are very happy about this decision and are looking forward to continuous collaboration, to the benefit of our users and the MariaDB Server project.

We think that this is a great decision for cPanel users because we at MariaDB have stayed true to the original values of MySQL, including:

  • Long term backwards compatibility
  • Painless upgrades and ease of use
  • Long term stable releases;

MariaDB Contribution Statistics, October 2023

We are in October, which means it has been 4 months since the last metrics report. It is, therefore, time for another quarterly metrics report (plus a bit more). The extra month was to allow for an announcement which is a prerequisite for this post, and it also means we are more or less aligned to real quarters. The major changes to this will come in the second half of this post, we have lots of additional data for pull requests. With that, let’s get started.

Mission Impossible: Zero-Configuration SSL

SSL (let’s call it that, even though SSL 2.0 and SSL 3.0 were long replaced by TLS 1.0–1.3 protocols) support was implemented in MySQL in 2001, so MariaDB (born in 2009) always had it. But over more than twenty years of SSL support there was one huge problem with it. It required tedious manual configuration, so most users never bothered and accepted the fact that their queries and data were sent unprotected. Which might have been slightly risky in 2001, but is definitely reckless in 2023.

The traditional approach

Let’s see. First, the user installing MariaDB or MySQL has to generate a private key and a certificate.

Run and operate MariaDB in Kubernetes with mariadb-operator

The introduction of the StatefulSet resource was a game changer when it comes to run stateful workloads in Kubernetes, introducing a wide range of features, including:

  • Predictable DNS names for each Pod, allowing one to individually address them in the network.
  • Stable persistent storage for each Pod, ensuring that each of them is bound to the same PersistentVolumeClaim.
  • Ordered graceful deployments and automated rolling updates.

However, this isn’t quite enough for running databases in Kubernetes in a reliable way. We are missing day 1 and day 2 operations, such as configuring high availability and scheduling backups, which is something not managed by vanilla Kubernetes.

Meaningful Response Metrics

There was a recent request by Eric Herman, the Chairperson of the MariaDB Foundation board, to add the time to first meaningful response for pull requests to the quarterly contributor metrics I generate and blog about. I thought this was a really good idea. There are a few problems with this, the first being the definition of “meaningful response”.

Meaningful Response

A “meaningful response” would likely be a response that adds value and shows that the pull request is being reviewed. The most accurate way to do this would be to manually record this using a set of criteria that defines what kind of responses are meaningful.

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 & IONOS: Improving performance for hosting

The MariaDB Foundation values our partnerships with our sponsors. Our partnership with IONOS allows us to get insight into how MariaDB Server is used and the direction it should take. As well as generally improving MariaDB Server in many different ways.

IONOS story

At CloudFest 2023, one of the first meetings we had was with Stefan Erkeling from IONOS. It was a very good meeting and it was great to see how much IONOS values our partnership. Stefan indicated in the meeting that there was a performance issue they were hitting and some advice was needed.
