Chapter7 MapReduce Types and Formats NamSoo Kim 1 MapReduce Types Map amp Reduce function types are as follows The map input key and value types K1 and V1 are different from the . Unlike sequential algorithms parallel algorithms cannot be analyzed very well in isolation One of our primary measures of goodness of a parallel system will be its scalability Scalability is the ability of a parallel system to take advantage of incr International Journal of Distributed and Parallel Systems (IJDPS) Vol.3, No.6, November 2012 150 are done by using least number of tables else excessive UNION queries are used to merge the tables sens International Journal of Distributed and Parallel Systems (IJDPS) Vol.3, No.6, November 2012 140 Type A: in a particular area, many motes within range of one another attempt to transmit simultaneously Supun .
