Parallel Querying with Non-Dedicated Computers

  title={Parallel Querying with Non-Dedicated Computers},
  author={Vijayshankar Raman and Wei Han and Inderpal Narang},
We present DITN, a new method of parallel querying based on dynamic outsourcing of join processing tasks to non-dedicated, heterogeneous computers. In DITN, partitioning is not the means of parallelism. Data layout decisions are taken outside the scope of the DBMS, and handled within the storage software; query processors see a “Data In The Network” image. This allows gradual scaleout as the workload grows, by using non-dedicated computers. A typical operator in a parallel query plan is… CONTINUE READING
