Scala is the only language that is statically typed, runs on the JVM and is totally Java compatible, is both object-oriented and functional, and is not verbose, thus leading to better productivity, less maintenance, and therefore more fun.

The system introduced in this paper is implemented using Scala, a programming language known for its concurrency and functional programming capabilities. After establishing the segmented trajectory storage system, we stored the Beijing taxi trajectory data and conducted several experiments. We used Spark to read and compute the trajectory data from the HBase of the system. The Spark NewHadoopRDD API allows for distributed reading of data from Hadoop and the creation of RDDs for concurrent computing.
