Neo4J backend (and other graph dbs)

[thomasp85]

This is really long down the roadmap but could be a very cool extension of dplyr's support for SQL backends

There is this package :https://cran.r-project.org/web/packages/RNeo4j/index.html but it just sends queries to the neo4j server. some sort of efficient translation to Cypher would be nice

Just updating that Colin is working on the general interface with neo4j in https://github.com/neo4j-rstats/neo4r
I'm thinking of rewriting some of the tidygraph verbs to support tidy manipulation of the graph in the database in neo4j-rstats/neo4r#4

[thomasp85]

If you want to spend some time on exploring this I would be very supportive. I tweeted a bit with colin about it when he announced the new neo4j package...

I'm still a bit unsure to what extend dplyr/sql verbs can be translated to cypher, but a starting point could be to just support very basic queries that returns a tbl_graph that can be further manipulated with tidygraph. Then it could be gradually extended from there...
