Celeste Horgan – Writes, 3 ways: Postgres, Apache Kafka® and Apache Iceberg™ #bbuzz

More: https://2026.berlinbuzzwords.de/sessi... Speaker: Celeste Horgan Learning new things is hard, but a useful way to think about new things is by comparing them to things you already know. In this talk, we'll compare writes between 3 different popular data services: Postgres, Apache Kafka and Apache Iceberg. In doing so, we'll learn a bit about the evolution of how we've thought of data storage as developers. The world of data services is evolving rapidly, with adoption of open table formats like Apache Iceberg™ picking up steam quickly. But “data services” is a pretty broad category, and none of these services is quite like the other. In this talk we’ll take a step back to look at three data services: Postgres, Apache Kafka and Apache Iceberg, and how they each handle writes. In doing so, we’ll trace a history through how data services have evolved in the world of distributed systems and big data. We’ll understand the key differences and similarities between these services. Finally, we’ll take a look at what’s coming next in the world of open source data, from Postgres and beyond. This session is meant as a refresher for existing data engineers as well as a primer for junior engineers: Most developers know a bit about Postgres but they might not fully understand the internals, and many engineers are getting heavily involved in Iceberg, but might not understand why it's relevant. ### Follow us on Social Media and join the Community!
