Validate existent documents on insert edge

[yguad]

When I insert a document with type edge, if I don't send the whole object referenced in _from and in _to it has a strange behavior. It would very good the possibility of to send only identifiers.
Is it possible to send the vertx references (identifier, for example "collection/1234") in the _from and _to fields and validate spring-data if they exist before inserting them?

Validating of edges in ArangoDB is only possible through named graphs and the corresponding graph REST API, which is currently not supported by Spring Data ArangoDB. There is an open feature request for that but no ETA.

ArangoDB spring-data allows me insert edges when the _from or _to referenced documents doesn't exists.
Thanks @mpv1989 for your reply. I would not like it use rest api. I found a way to implement using directly the arangodb driver but it would be interesting to configure it using spring data.

Since ArangoDB graphs API does not support overwriting (https://www.arangodb.com/docs/stable/http/gharial-edges.html#create-an-edge), it is not suitable for implementing save method in ArangoRepository, which requires insert/replace behavior.
Therefore for the moment, support to named graphs API can only be implemented in the ArangoTemplate API.

Closing for now, please refer to #76 for further discussion.
