TRANSMUT-SPARK: Transformation Mutation for Apache Spark
Joao Batista de Souza Neto, Anamaria Martins Moreira, Genoveva Vargas-Solar +1
We propose TRANSMUT-Spark, a tool that automates the mutation testing process of Big Data processing code within Spark programs. Apache Spark is an engine for Big Data Processing.…
An Abstract View of Big Data Processing Programs
Joao Batista de Souza Neto, Anamaria Martins Moreira, Genoveva Vargas-Solar +1
This paper proposes a model for specifying data flow based parallel data processing programs agnostic of target Big Data processing frameworks. The paper focuses on the formal abst…
An Algorithm for Context-Free Path Queries over Graph Databases
Ciro M. Medeiros, Martin A. Musicante, Umberto S. Costa
RDF (Resource Description Framework) is a standard language to represent graph databases. Query languages for RDF databases usually include primitives to support path queries, link…
