Consider a parallel system with shared nothing architecture. Assume that there are threeprocessors PO$,$ P$1$ and P$2$ with associated disks DO$,$ DI and D$2$ 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 ofparallel external sort merge.
