Event Streams in Action

This book describes basic terms related to the topic, by solving simple and fictitious problems using Amazon IaaS services and some open source tools such as Redshift, Kinesis, Kafka, Scala, Spark, Avro.
I think that by simply removing the tool-centric content, the whole concepts could be summerised in 2 or 3 blogposts. Anyway! This book is a simple and easy-to-read book for someone who's new to the topic.
