Suppose you wish to handle a workload consisting of a large number of smalltransactions by using shared-nothing parallelism.a. Is intraquery parallelism required in such a situation? If not, why, andwhat form of parallelism is appropriate?b. What form of skew would be of significance with such a workload?c. Suppose most transactions accessed one account record, which includesan account type attribute, and an associated account type master record,which provides information about the account type. How would you partitionand/or replicate data to speed up transactions? You may assumethat the account type master relation is rarely updated.
