Session
An Apache Spark query's journey through the layers of Microsoft Fabric
A deep-dive session about Spark internals, where we explore how queries are executed in Apache Spark and within the layers of Microsoft Fabric.
We will cover:
* Spark SQL and Catalyst
* A note on Tungsten
* Delta Lake
* Parquet files
These insights will be supported by glimpses into the official Apache Spark source code on GitHub.
The takeaway should be a better understanding of how queries are executed and some tools for problem-solving and optimizing for speed or cost.
