At long last, @chris.blue and I have submitted the final manuscript of Designing Data-Intensive Applications, second edition, to the publisher. There is always more that could be improved but at some point we just have to call it done. Now it goes into production; probably shipping in ~4 months.

So #databs, who wants to try S3Tables?

I've created a Datafusion distribution with support for S3Tables that you can run from the command line. This is all you need:

frostbow -u arn:aws:s3tables:us-east-1:123456789:bucket/my-bucket-prefix

Check it out the example: github.com/JanKaul/fros...

Does anybody have an idea how S3 Tables can achieve 3x performance compared to regular Iceberg tables on S3?

Does it work similar to the object-store file layout?

This has been a long time coming. After the concerted efforts many engineers from across companies and across continents, posted some great benchmark results

There is a discussion on the Top 2025 Data Trends with Matt Housley today. Could be interesting. #databs

I recently gave a talk about Iceberg Materialized Views at Chill Data Summit London.

I think Iceberg Materialized Views can really revolutionize the way we approach data transformations.
