I haven't used but have a seen a few Hadoop implementations. If you do research on Sharding that's the kind of db where the data is split across nodes not redundantly. http://www.nathankerr.com/projects/parallel-gis-processing/alternative_approaches_to_parallel_gis_processing.html http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3814183/ Then of course depending on your needs there are plenty of MPI compatible libraries in various languages.
