Functional Stream Processing in Scala by Zainab Ali (Early Access)

Modern business applications are moving towards incremental processing. We design realtime data pipelines, event-driven architectures, reactive systems, and use stream-based I/O with databases, files and websockets. You may have heard of streams in media, but stream processing has many wider applications.

Just as functional programming has transformed the way we build applications, functional stream processing lets us write simple, safe, scalable incremental pipelines.

This book is a practical deep-dive into building reliable stream processing pipelines with Scala 3 and fs2.
