I'm currently in the process of drafting a book about modern data engineering. Data pipelines and data warehouses have changed drastically in the last five years and I feel the few books on the subject are drastically outdated. I figured I'd just start with content and work my way into the logistics of the actual publishing process. This, and the comments in this thread, are a huge help on the logistics side. Thank you!
