The promises they make are really tempting. However, when I experimented with Blazegraph last year, it ended up stuck more often than I could count, whether during bulk import or in answering some ad-hoc SPARQL queries.<p>I can imagine that with extensive tuning, BlazeGraph provides a good database. Just don&#x27;t expect it to have the polish and convenience of a modern RDBMS or a shiny NoSQL store :)
