What both should've said: size in bytes 😉

It's possible 1 > 100 given the average size 🤷

If you’re even remotely interested in learning Flink or other data streaming technologies, join the waitlist - it’s the only way to get early access (and discounted pricing).

So today I’m announcing Data Streaming Academy: the best place to master data streaming technologies. I’m going to kick off with a hands-on, deeply technical development bootcamp dedicated to Apache Flink: Advanced Apache Flink Bootcamp.

This past year, however, has been one of exploration: building a developer tooling company, consulting, and doing a lot more writing. So I started thinking: maybe this is the right moment to experiment with education too.

Over the past few years, many people I've spoken with have suggested the same thing: “You should write a book or launch a course.” It’s something I’ve always taken seriously (even started writing a book during Covid), but the time commitment never quite aligned with having a full-time job.

IMO, calling it "foundation for modern data infrastructure" is a stretch. You can say this about object storage or Parquet, but not Fivetran.
