Elasticsearch storage adapter for Gun DB :gun:

Gun-Elastic

Elasticsearch native persistence layer for Gun, a realtime, distributed, offline-first, graph database engine.

This gun storage adapter interfaces with Elasticsearch using an extended flint node strategy:

• get request expect to read an entire Gun node.
• put requests write an entire Gun node.
  • node key-value structure (soul,relation,field,value,state) optionally saved to secondary index

THIS WORK IS EXPERIMENTAL WORK IN PROGRESS! USE AT YOUR OWN RISK!

Comments and PR/Contributions are super welcome!
