The Internals Of Apache Spark 3.0.0

Welcome to The Internals Of Apache Spark online book!

I’m Jacek Laskowski, a freelance IT consultant specializing in Apache Spark, Apache Kafka, Delta Lake and Kafka Streams.

I’m very excited to have you here and hope you will enjoy exploring the internals of Apache Spark (Core) as much as I have.

I write to discover what I know.
— Flannery O'Connor
