Parallelizing SAIGE Across Hundreds of Cores
As population genetics datasets grow exponentially, it is becoming impractical to work with genetic data without leveraging Apache Spark™. There are many ways to use Spark to derive novel insights into the role of genetic variation on disease processes. For example, Regeneron works directly on Spark SQL DataFrames, and the open-source Hail package can be...
Diving Into Delta Lake: Schema Enforcement & Evolution
Think back to when you were in high school - so fresh and full of ideas. Since then, undoubtedly, both the world and the way you see things have changed in many ways, as you have gained new experiences. Data, like our experiences, is always evolving and accumulating. To keep up, our mental models of...
Guest Blog: How Virgin Hyperloop One reduced processing time from hours to minutes with Koalas
At Virgin Hyperloop One, we work on making Hyperloop a reality, so we can move passengers and cargo at airline speeds but at a fraction of the cost of air travel. In order to build a commercially viable system, we collect and analyze a large, diverse quantity of data, including Devloop Test Track runs, numerous...
Diving Into Delta Lake: Unpacking The Transaction Log
The transaction log is key to understanding Delta Lake because it is the common thread that runs through many of its most important features, including ACID transactions, scalable metadata handling, time travel, and more. In this article, we’ll explore what the transaction log is, how it works at the file level, and how it offers...
Productionizing Machine Learning with Delta Lake
Try out this notebook series in Databricks - part 1 (Delta Lake), part 2 (Delta Lake + ML) For many data scientists, the process of building and tuning machine learning models is only a small portion of the work they do every day. The vast majority of their time is spent doing the less-than-glamorous (but...
