59 percent of the Hadoop scenarios described were implemented with “small” data volumes up to 25 terabytes (TB). Scenarios exceeding 1 petabyte (PB) are few and far between (1 percent). As expected, higher data volumes are anticipated in the near future (i.e. the next 12 months).
Companies start with smaller-scale Hadoop initiatives in order to first see the potential for further development. The largest increase was reported among scenarios exceeding 25 TB.
