⁠Introduction

OntopSpark⁠ is an extension of the Ontop Ontology Based Data Access (OBDA) system. OntopSpark uses Apache Spark as a query processing engine for accessing the data stored in data lakes. The integration of a distributed data processing engine such as Apache Spark allows exploiting the Ontop data integration capabilities at its maximum potential, as it brings all the advantages of velocity and parallel computation typical of a distributed system to the task of solving a SPARQL query.

⁠Environment Variables

The OntopSpark docker image has been created starting from the official Ontop source code, therefore the ENV variables to be configured are the same described in the offical Ontop image⁠ readme.

⁠Tutorial

For learning how to use OntopSpark inside a data analysis pipeline, you can follow this demo⁠.
