Never heard of ToroDB. Just checked out the website and it looks interesting, however the tagline "The first NoSQL and SQL database" is untrue. At least OrientDB has had both schema+schema-free and SQL + NoSQL querying interfaces. That is, you can optionally supply a schema for your documents. IIRC you could choose either schemaless, schema or mixed (where mixed allows fields not in the schema to exist as schemaless fields). The default query language was SQL with "enhancements" (to allow for graph traversal), but you could also query with Gremlin. Not sure if this is still the case or not as I don't use OrientDB. The above was true in 2012 and possibly a lot earlier. I see ToroDB's first Github commit was in 2014.
