The hyper-db folks do great work. Indeed, Huanchen collaborated with Viktor Leis (one of the senior folks on HyPer) on the SuRF "Succinct Range Filter" (think Bloom filter but for range queries) work: http://www.cs.cmu.edu/~huanche1/publications/surf_paper.pdf http://www.cs.cmu.edu/~huanche1/publications/surf_paper.pdf and github: https://github.com/efficient/SuRF https://github.com/efficient/SuRF and both Viktor and Thomas Neumann's work in this area is fantastic and everyone should go read it. :) The code for several of Huanchen's projects is available in our group's github repo: https://github.com/efficient/ https://github.com/efficient/ The order-preserving compression work outlined in his thesis will be appearing soon at SIGMOD, but there's no need to wait for it, since it's roughly the same in both. We'll get the source to that released by the time of SIGMOD.
