In late 2018 I gave a workshop about Spring 5’s new features to Tikal’s full-stack community. The most talked-about feature in Spring 5 was Reactive Spring.
As I was preparing the code samples and lessons for the workshop, I realized I was quite limited with the options for a database example. I had two options:
I chose to work with MongoDB, so I could present a fully reactive web application.
But now the struggle…
In databases, change data capture (CDC) is a set of software design patterns used to determine and track the data that has changed so that action can be taken using the changed data.
Lately I’ve been working on a CDC (Change Data Capture) system, that tracks changes from Postgres-based databases and sends them to another destination.
This is a very common scenario for a CDC — syncing data between databases. Thus my research started with checking what other, including Debezium, use to capture data changes from Postgres, which resulted with WAL.
Write Ahead Logs (aka WAL), are the transaction logs…

I’ve been coding in Java for many years and it became my main programming language in 2008. I like Java, I enjoy coding in Java, but I have to keep up. I tried Scala, but after trying to learn it I came to the realisation that it is not my style.
The services are small Spring +…
