I've been listening in and also followed the Slack channel. It's organised by (both?) featurestore.org and Hopsworks. Anyways, the format of answering questions in the Slack (this time it's featurestore.org's) after the talks was appreciated.
Hope to get the recordings afterwards..
The first conference about feature stores for machine learning is happening now and can be seen live on YouTube. The topic of the upcoming session is building versus buying a feature store, and it is discussed by companies including Uber, Wildlife Studios, Via, Hopsworks and Varo Bank.
A very nice chance listening industry leaders' ideas on this emerging area.
