A Change-Data-Capture use-case: designing an evergreen cache

English session - Beginner

It’s easy to set up a cache in front of a database to improve speed. If the app is the only component that writes to the database, it’s straightforward to keep the cache in sync with the database but that happens rarely. Traditional sync techniques all have issues. Change-Data-Capture is a new approach that fix those issues.

In this talk, I’ll describe an easy-to-setup architecture that leverages CDC to achieve an evergreen cache.

English session - Intermediate

In this talk, I’ll demo how to update a Spring Boot app deployed on a Kubernetes cluster with a database schema change, while keeping the service up during the entire update process.
