Hi, I'm very interested in this subject because I would like to export parquet data from HDFS to Vertica (using VSQL). I'm planning to work on it next quarter, but I will be very happy to help you on this subject (review, testing).

Nong and Wes, It'd be interesting to know your goals for parquet-cpp. The Vertica database already supports optimized reads of ORC files (fast c++ parser, predicate pushdown, columns selection etc). We'd like to do the same for parquet.
