We finally scheduled some time to talk to David Oppenheimer. David, a software engininer at Google, has been working on scheduling there since 2007, including on both Borg and Omega. That experience naturally led to him working on the Kubernetes scheduler, as well as starting SIG Scheduling.

Do you have something cool to share? Some questions? Let us know:
