Spark - What is it?

There's an engine called Apache Spark. It's in Databricks, Synapse Spark Pools, Mapping Data Flows and a whole raft of other tools and platforms... But what is it?

If you're a data architect, solution designer, or simply want to know what this whole big data thing is about, this session is the first step you need!
