2019 Zenodo  
We analyze the state-of-the-art for big data benchmarking considering different challenges which range from preserving the 4V properties of big data to streaming and scalability issues.  ...  We believe that it would be better to follow a layered design where the user interfaces are at the top in order to provide easy access to the benchmarking for the user.  ...  Benchmarking RDF systems presents different challenges than the ones posed in relational database engines. As a result, existing relational benchmarks are not really suitable for RDF benchmarking.  ...
