The Immutables team is deep into design discussions, as they work to build a relational database on top of content-addressable immutable objects with the Scality S3 Server. Team lead Ignacio (Nacho) Corderi is huddled with Marc Segura and Michael McThrow to build this ambitious extension. Nacho, who was on the original Kinetic team at Seagate, came by to see friends here on Friday night, then got caught up in the wave of enthusiasm and joined the Hackathon. Nacho is a graduate student at UC Santa Cruz, and an engineer at Exablox. Michael McThrow, also a graduate student at UC Santa Cruz, signed up for the Hackathon on the recommendation of a friend and professor at the school. He came for the practice and the contacts, as he’s looking for his next gig. Marc is on the S3 Server team at Scality.
