Feathr: LinkedIn's High-performance Feature Store // David Stein // Coffee Sessions #120

Показать описание

MLOps Coffee Sessions #120 with David Stein, Senior Staff Software Engineer at LinkedIn, Feathr: LinkedIn's Enterprise-Grade, High-Performance Feature Store co-hosted by Skylar Payne.

// Abstract
When David started building Feathr, Feature Stores did not exist. That was not a term floating around at all. This was definitely one of the OG Feature Stores for sure!

We hear how the LinkedIn team got to this point, having an open source release, and how they used LinkedIn as an incubator to build a great product.

// Bio
David Stein is a tech lead at LinkedIn working on machine learning feature infrastructure. He is the original architect of Feathr and continues to contribute to its development as well as to other parts of LinkedIn's machine learning platform.
