This is a triplestore based on RocksDb. I have been working on this for a while. Adding more query capabilities. The query language is JSON based (as opposed to SPARQL) and I hope easier to understand and reason about. Don't get me wrong, I think SPARQL is very powerful, but I am focusing on how we can think of normal JSON documents as graph structures and easily query them.
The read/write performance is also quite good because the underlying store is RocksDb - using the default configurations for now.
Looking for users, feedback and contributions. Hope you enjoy it.
