Assume you want to use shared-nothing parallelism to manage a workload with a large number of tiny transactions. a. Is intraquery parallelism necessary in this case? If not, why not, and what kind of parallelism is best? b. With such a workload, what kind of skew would be significant? c. Assume that most transactions visited a single account record with an account type attribute and an accompanying account type master record that contains account type information. To speed up transactions, how would you partition and/or replicate data? It's reasonable to suppose that the account type master relationship isn't altered very often.
