In my article Kafka Versioning I have briefly covered different ways of handling versions and using schemas to manage changes to the data structures. However, merely understanding these concepts falls short when operating within an environment characterized by numerous teams and bounded contexts. It is necessary to identify patterns and principles for navigating model changes successfully.
I have worked with DDD for many years, and learned to not share databases and to use anti-corruption layers between systems and services. Therefore, I was at first very reluctant to connect Kafka directly to the databases. Wouldn't that recreate the monolith that we have been working so hard to get rid of?
Defining an event may seem straightforward, and when I wrote my first Kafka article I thought of all events as business events. I've now realized that there are various types, with Change Data Capture (CDC) events emerging as one of the most prevalent.
I'm filled with Christmas cheer. Because yesterday, we brought in the Christmas tree, and had a peaceful time with the family wrapping the Christmas gifts. While still in this mood, I want to tell you about my mum's Christmas on a small farm name Månstuga in the deep forests of Värmland, in Sweden.
The Intelligence & Efficiency Team was formed two years ago. It is a digital, remote team that is spread out over several cities in two countries. When I joined them, their software was new and just about to go live. We rolled it out at the same time as we added a lot of new features. And, we did it under extreme time pressure.
When developers take shotcuts or decrease the quality to gain time, they will cause a technical debt. By doing nothing and letting the system age, the technical debt is growing too.
In a legacy system, what is it that you spend absolutely most time on? I would say, understanding code and finding out where to do a change. Most of us have been in the situation that we spend hours or days looking for exactly one single line that would be changed in a million line code base.
One year ago, we new little about what 2020 would bear in mind for us. But at New Year’s Eve, me and my husband made a decision to do something that we had been planning for a long time. We would relocate from Gothenburg, where we had lived for more than 25 years, to London!
I recently heard about a project where the code was written in C#, but where they implemented the unit tests in F#. They did so because they wanted to learn and evaluate F# in a protected environment. I thought that sounded like a very good idea and wanted to try.
Dear Newbie, I know you struggle a bit with your new role and how to become a successful professional programmer. I think the best would be if I just told you, already now at start, what you need to know!
