Consider a parallel system with shared nothing architecture. Assume that there are three processors PO, PI and P2 with associated disks D0, D1 and D2. Assume that the records with the following keys are partitioned among the disks such that record with key, k goes to disk Di if k mod 3-i: 26, 16, 27, 15, 30, 18, 14, 25, 10, 9, 8, 24,5 Assume parallel external sort merge is used to sort the records. Depict what will be the contents of the disk before sorting. Assume that the same partition vector [11, 20] is used in the merge phase. Show snapshots of data distribution after the various steps of parallel external sort merge.
