This database contains about 35 million records (companies) with different fields to select on (Number of emplyees, Activity code, Geographical codes, Legal form code, Turnover figures, Year of establishment and so on) Performance is very important for this online app. If one makes a selection with different criteria, the number of selected records should be on your screen in (milli) seconds. We are not sure if Hadoop will be a good choice, for fast results we need a good indexed relational database in our opinion… Can anybody advise me? Thanks!
