On multi-core machines – which is the majority of the hardware nowadays – and in the cloud, we have multiple cores available for use. The queries are similar to those I’ve used in older blog posts comparing MySQL and Apache Spark performance ( [link] ). With faster disks (i.e. AWS Aurora (based on MySQL 5.6)
