We have been implementing a Key-Value Store based MapReduce System, called SSS, which enables quick MapReduce iteration by employing Owner-Compute Rule. We have been employing sequential pattern mining using PrefixSpan method as an evaluation target. The performance so far was not satisfactory for large sized data, however. This paper proposes a new implementation technique for PrefixSpan method over MapReduce. In the proposed method, we moved bound operation from Reducer to Mapper, eliminating data transfer cost between Mapper and Reducer. As a result we confirmed that the new technique showed 60 times speedup for SSS and 3 times speedup for Hadoop. |
