Data will power every piece of our existence in the near future. I collect “Data Points” to help understand & shape this future.

The data world is in turmoil, so I love every piece of experience I can get my hands on. I really enjoyed this article by Prukalpa Sankar, featuring a modern data stack with Snowflake, Atlan, and Tableau.

I’ll just share two quotes and would simply recommend you to read the whole article. It’s really well written.

So after modernizing the data warehouse, they noticed that we need more, education, data cataloging, etc. It’s a great example of todays’ journey for data organizations.

I’ve been saying again and again that I think the data space will be dominated by open source solutions, because of the “snowflake problem”, the problem that every data setup inside companies is completely unique.

So it’s great to finally get an article from the guys behind airbyte on that topic that backs this up with their experience. They focus very much on the ETL use case, where I think this conclusion applies to the complete data case. But I really like how they put their experience and 200 company interviews into this form and show the exact road ETL has to go on in the future.

I also like the way they think about their CDK because the CDK is really an essential part of the incentive structure for their open source project. Great to see that even though they are at the very beginning, they got a good vision of where they need to go.

I do think though, in the future, they’ll need to spend more time on the high-level structure of the data space & their open-source side (because after all, I think ETL is a system that is set up to be obsolete in 5–10 years). But I’m sure they will get there.

Anna Geller wrote a good piece on airflow and data orchestrators in general. Here’s a little summary of her points:

The strength of Airflow lies undoubtedly in the community, the support & extensibility that comes with that. However, as Anna writes, Airflow also brings a bunch of weaknesses.

There’s no native versioning of flows, it’s very unintuitive for new users, it’s got a configuration overload and is hard to use locally. All things that basically make it hard to develop fast. It’s also where some of the new tools shine. Prefect focuses on taking lots of this out of your hands. Dagster has a great testing concept and is much easier to handle when it comes to developing new flows.

The problems at setting up Airflow at production are to my knowledge mostly mirrored at both prefect & Dagster so I’m not sure one can consider that a weakness of airflow but more of the category of tools.

However, there are managed solutions available that take away quite a bit of the hassle. If you’re looking for a data orchestrator, take a look at Annas article.

Thanks for reading this far! I’d also love it if you shared this newsletter with people whom you think might be interested in it.

I finally got around to holding a talk on data meshes, focused on being as concise as possible while still giving a bit of my bigger view on things. You can find the slides here:
