Kinda. So first i went for a standalone application back than to use it as storage/database. This part is archived now. it was released under:
https://github.com/voodooEntity/slingshotdb
At this point i think its important to mention that its nativly an in-memory graph database/storage.
At some point (4-5 years ago) i decided to change the way i handle it. Since im using the storage in many private projects, and there was no real traction (while also maintaining a database is quite some work) i decided i gonne change the way i handle it away from a standalone database to a library that works as an in-memory graph storage.
Also i added a custom query language including builder (the queries are 100% json compatible so you can in theory build queries from whatever language and transmit it via json.
Currently im completly reworking the query parser but since this is a privat project and im the only maintainer it may take some to to finish it. The update will takle some smaller bugs in the query parser that can occur on very complex nested queries and also will optimize query speeds. I cant provide a date when the update will occure i only can say it will (because i need it myself).
Finally said: The strength of gits is to be very fast (hence in memory handling) and easy to use from golang. Its threadsafe by default.
