Suppose that a static hash file initially has 600 buckets in the primary area and that records are inserted that create an overflow area of 600 buckets. If we reorganize the hash file, we can assume that most of the overflow is eliminated. If the cost of reorganizing the file is the cost of the bucket transfers (reading and writing all of the buckets) and the only periodic file operation is the fetch operation, then how many times would we have to perform a fetch (successfully) to make the reorganization cost effective? That is, the reorganization cost and subsequent search cost are less than the search cost before reorganization. Support your answer. Assume s = 16 ms, rd = 8.3 ms, and btt = 1 ms.
