The established VLDB PhD Workshop series is a unique opportunity for graduate students to present and discuss their research in the context of a premier international conference. The workshop provides a forum that facilitates interactions among PhD students and stimulates feedback from more experienced researchers|not only in terms of diligent paper reviews but also at the conference site. Following the call for papers, 24 authors submitted their papers for presentation at the workshop. Of these, the program committee carefully selected a total of 8 papers which you will nd bundled in this volume: Sergey Dudoladov E cient Fault Tolerance for Massively Parallel Data ow Systems Shadi A.
