Designing good mapreduce algorithms
WebNov 20, 2024 · There are two parameters that represent the trade-off involved in designing a good MapReduce algorithm: the first one is the reducer size, denoted by q, which represents the size of the largest list of values associated with a key that a reducer can receive. The second parameter is the amount of communication between the map step … WebJan 10, 2011 · Download PDF Abstract: In this paper, we study the MapReduce framework from an algorithmic standpoint and demonstrate the usefulness of our approach by …
