Delta Engine is annouced in Spark AI Summit 2020 which is Apache Spark-compatible vectorized query engine to take advantage of modern CPU architecture promising 16x performance improvement.

Today, we announced Delta Engine, which ties together a 100% Apache Spark-compatible vectorized query engine to take advantage of modern CPU architecture with optimizations to Spark 3.0’s query optimizer and caching capabilities that were launched as part of Databricks Runtime 7.0. Together, these features significantly accelerate query performance on data lakes, especially those enabled by Delta Lake, to make it easier for customers to adopt and scale a lakehouse architecture.

Scaling Execution Performance

One of the big hardware trends over the last several years is that CPU clock speeds have plateaued. The reasons are outside the scope of this blog, but the takeaway is that we have to find new ways to process data faster beyond raw compute power. One of the most impactful methods has been to improve the amount of data that can be processed in parallel. However, data processing engines need to be specifically architected to take advantage of this parallelism.

In addition, data teams are being given less and less time to properly model data as the pace of business increases. Poorer modeling in the interest of better business agility drives poorer query performance. Naturally, this is not a desired state, and organizations want to find ways to maximize both agility and performance.
