PublicS2X
PublicS2X (SPARQL on Spark with GraphX) is a SPARQL query processor for Hadoop based on Spark GraphX. It combines graph-parallel abstraction of GraphX to implement the graph pattern matching part of SPARQL with data-parallel computation of Spark to build the results of other SPARQL operators.PigSPARQL
PublicPig Latin is a high-level language developed at Yahoo! Research designed for data analysis tasks, which is automatically transformed into MapReduce jobs and executed in a Hadoop cluster. PigSPARQL is a translation from SPARQL 1.0 to Pig Latin, which allows to execute SPARQL queries on large RDF graphs with MapReduce.S2RDF
PublicS2RDF (SPARQL on Spark for RDF) is a SPARQL query processor for Hadoop based on Spark SQL. It uses the relational interface of Spark for query execution and comes with a novel partitioning schema for RDF called ExtVP (Extended Vertical Partitioning) that is an extension of the Vertical Partitioning (VP) schema introduced by Abadi et al. ExtVP en…Sempala
PublicSempala is a SPARQL-over-SQL approach to provide interactive-time SPARQL query processing on Hadoop. It stores RDF data in a columnar layout (Parquet) on HDFS and uses either Impala or Spark as the execution layer on top of it. SPARQL queries are translated into Impala/Spark SQL for execution.
