In the long having a triple based API does not mean you need to have a single triple table based storage.

In the SPARQL world that is actually quite interesting as different systems have very different data layouts while maintaining the same basic query language.

Comparing to the top post. I think triple systems are much more scalable than Neo4J even if not as popular. There are a few triple systems with a trillion node benchmarks. Even more with a 100 billion plus. Neo4J has at most ~34 billion relationships, and no more than 274 billion triples. Those are hard limits per current Neo4J documentation. But I have not heard of any Neo4j systems in production at that scale. While I know of at least one SPARQL system that is running with 4 trillion edges (http://allegrograph.blogspot.ch/2015/11/allegrograph-news-no...).
