This paper discusses Trovares xGT, a property graph engine. It is not a graph database per se. However, it will compete with graph databases for query processing against extremely large graphs. Briefly, the concept is that you load your data – currently it must be in CSV format – into memory. This is done in parallel so that ingestion rates are rapid. The software will convert the loaded data into graph format, ready for exploration. There is a free trial version of the product available on AWS (Azure in progress) with anything from 1Gb to 4Tb on an hourly basis. Or you can arrange an on-site proof of concept.
