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.

Hi, we from the MariaDB Foundation are having a set of meetings with developers and senior managers from all over the world. We’d like your feedback on the Good/Bad/Ugly bits of MariaDB Server as you see it, and generally what we could be doing better. Please leave comments here, or Reddit, or email discuss@lists.mariadb.org (subscription), or email me directly daniel@mariadb.org.
This will be discussed at the MariaDB (Un)conference 2023 and MariaDB Server Fest 2023 which you are welcome to attend also to state your cases in person.

“The only workload that matters is my production workload” (for all values of “my”). So you can manage this responsibility, SCARY is a software tool which aims to take the uncertainty out of change; software, configuration and hardware changes. This is very early in development, but projects have to start somewhere.
SCARY takes a read view of the production database query execution, and does the equivalent query on a copy of the production database, that has differences. The query speed, query plan, data result (eventually) will be recorded along with what went on in production.

MariaDB Foundation is having its next planning session for the MariaDB Server Roadmap at our MariaDB Unconference Tue-Wed 3-4 October 2023.
All key contributors will be there
This will be a top-level meeting with representatives of all key contributors to MariaDB Server. From MariaDB plc, we will have CTO Jonah Harris and VP Server Engineering Sergei Golubchik representing management and resource allocation. But MariaDB Server is not a one-vendor product. We expect similar level representation from our second-biggest contributor, Amazon, and we also have confirmed roadmap attendance by Webpros, Alibaba, IBM, Intel, and others.

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.

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.

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 Server 11.0 was recently released and its Docker Official Image didn’t include mysqladmin which broke the healthcheck in a few usage scenarios. This surprised some people in the change of behaviour. We have observed a number uses of the mysql names in containers, custom healthchecks and some /docker-entrypoint-initdb.d scripts. To help use these correctly, lets talk about what is available in the containers to help perform healthcheck and initialization functions.
On healthchecks, HEALTHCHECK isn’t there in Docker Official Images (for reasons), however the MariaDB Server container does have a healthcheck.sh script.
