During Larry Ellison's recent interview with Ed Zander at the Churchill Club in Silicon Valley, someone asked Larry Ellison what he thought was the most significant distruptive innovation that Oracle was paying attention to.

Larry Ellison said: "Flash".

Apparently, Oracle is taking flash very seriously. They already have a flash-based Oracle database product that is shipping.

And with the Sun acquisition, Oracle now owns MySQL.

RethinkDB needs to move ahead fast.
