hypertable (store data and metadata in different access groups, basically different files on disk but in the same table) on top of QFS for distributed file system in reed-solomon replication(for ~more efficiency) you can keep n-versions(miscrosecond timestamps), sorted compressed data on disk for fast range reads, you can compress and group in blocks differently across access groups(access groups are just groups of columns) it was based on bigtable, which was written to store the crawling data(like you & waybackmachine?) for google search
