This year we started a research project, named AROM, in collaboration with the Université Libre de Bruxelles. We wanted to evaluate a Data Flow Graph (DFG) processing framework and compare it to a traditional MapReduce (MR) one. In addition, we analyzed high level data manipulation languages such as PigLatin  and investigated whether a MR approach introduces an important overhead in the transformation of data operations to the physical execution plan. Going further, we analyzed a typical class of data analytic, the pipelines jobs and we studied the adequacy of DFG for ease of use and performances. Finally, we used functional programming in order to introduce higher order functions to simplify the expression of jobs and to promote the re-usability of operators.
