The blog post doesn't mention this, so I thought I'd point this out. One of the paper's authors is Martin Kleppmann, who wrote the very good https://dataintensive.net/ book.
Kleppmann co-created/major contributor to Apache Kafka along with Jay Kreps and Neha Narkhede. He also co-founded Rapportive, a YC company acquired by LinkedIn, along with Rahul Vohra, who is presently the CEO of Superhuman.
And don't miss "Turning the database inside out with Apache Samza"
