SIGMOD 2009 (a top tier DBMS research conference) is being held in Providence, RI, at the end of this month (the week of June 29th). Column-stores seem to be taking off as a mainstream research topic, as I've counted at least 5 talks at SIGMOD on column-stores (including an entire session!). Make sure you get to SIGMOD by (at least) Tuesday morning though, as "Query Processing Techniques for Solid State Drives", by Dimitris Tsirogiannis, Stavros Harizopoulos, Mehul Shah, Janet Wiener, and Goetz Graefe, is being presented in the first research session slot on Tuesday (research session 2). It doesn't look like it from the title, but trust me, it's a column-store paper. The controversial Vertica / parallel DBMS vs Hadoop benchmark paper is being presented in research session 5 (Sam Madden, an excellent speaker, is presenting the paper), and the aforementioned column-store session (with 3 column-store papers) is in research session 8 at the end of the day Tuesday.
But if you get there early don't leave early! I will be giving a 30-minute talk on column-stores in the awards session at the very end of the conference (I don't believe the talks in this session have been officially announced yet, but I'm indeed giving one of the talks) which goes until 5:30PM on Thursday, July 2nd.
