Martin Kleppman, best known as the author of the fantastic book Designing Data Intensive Applications, talks about modern data systems, his current work on collaborative software and, most interestingly, the second edition of DDIA.<p>He mentions that in the new edition, there will be more information and focus on cloud services, and some "dead" technologies like Hadoop MapReduce will be omitted.<p>In general, however, Martin is happy that most of the book is still fundamental knowledge and ages pretty well.<p>A bit not as well known is the fact that Martin is doing research in collaborative, so-called "local first" software (think, CRDT) where local devices play the central role.<p>In general, I think Martin Kleppman is a terrific writer and teacher.
