@Pulquero AFAIK the two main problems with Blazegraph are: 1. The project is not really active anymore: https://github.com/blazegraph/database . The reason is that the Blazegraph team was acqui-hired by Amazon a few years ago, and Blazegraph essentially became Neptune, Amazon's proprietary graph database https://en.wikipedia.org/wiki/Blazegraph 2. Blazegraph has several performance issues. The Wikidata Query Server at https://query.wikidata.org uses a variety of hacks to make Blazegraph usable for typical queries. For example, there is a dedicated SERVICE to handle the huge rdfs:label predicate and the original Wikidata is pre-processed in various ways to make it more palatable for Blazegraph. But it's still rather slow compared to other engines. Queries with large result sets always time out.
