Abstract

This paper treats the file redundancy issue in distributed database systems asking what is the optimal number of file copies, given the ratio r of the frequencies of query and update requests. To draw a general conclusion applicable to a wide variety of practical distributed database systems, simplified network models are constructed, and optimal number of file copies, as well as their locations, to minimize the communication cost is ccmputed. By examining various network types, we plot the optimal number of file copies as a function of the ratio r.

Our conclusion is that a single copy suffices under moderate condition, and it is disadvantageous to have more than a few copies unless the frequency of query requests is unduly higher (e.g., 50 times) than that of update requests.
