The Internals Of Apache Spark 2.4.5

Welcome to The Internals Of Apache Spark online book!

I’m Jacek Laskowski, a freelance IT consultant, software engineer and technical instructor specializing in Apache Spark, Apache Kafka, Delta Lake and Kafka Streams (with Scala and sbt).

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
I’m also writing other books in the "The Internals Of" series about Spark SQL, Spark Structured Streaming, Delta Lake, Apache Kafka and Kafka Streams.

Expect text and code snippets from a variety of public sources. Attribution follows.

Now, let me introduce you to Apache Spark.
