The Internals of Spark SQL (Apache Spark 3.2.0 (RC2))

Welcome to The Internals of Spark SQL online book! 🤙

I'm Jacek Laskowski, an IT freelancer specializing in Apache Spark, Delta Lake and Apache Kafka (with brief forays into a wider data engineering space, e.g. Trino and ksqlDB, mostly during Warsaw Data Engineering meetups).

I'm very excited to have you here and hope you will enjoy exploring the internals of Spark SQL as much as I have.
