What drives the evolution of the Milky Way's disk?

Data from the recently launched Gaia satellite in combination with data from large spectroscopic and asteroseismology surveys will allow great progress in unraveling the evolutionary history of the Milky Way disk over the next decade. Here, I briefly review the progress made with observations in the solar neighborhood in constraining the main processes involved in the formation and evolution of the Galactic disk. I then focus on recent new insights on the chemo-dynamical structure of the disk from SEGUE and APOGEE data. I conclude by summarizing the current state of knowledge and what evolutionary actors best explain the data that we have now, and by looking forward to the most informative measurements that Gaia and other surveys can make.
