Is there some ways to bulk load graph data into arangoDB?

[Yichao Li]

According to the docs, I could only find ways to load data in collection/document ways.

[Dave Challis]

You can also import graph edges in the same way (i.e. they're just an edge collection), so can import some documents, then bulk import edges to that collection with e.g.:

{"_from":"someCollection/1", "_to":"someCollection/2"}

etc.

Please have a look at ArangoImport:

https://www.arangodb.com/docs/stable/programs-arangoimport.html

If you prefer to roll your own, you can use the bulk document API:

Please Note that in ArangoDB Vertices are regular documents, and Edges are basically Documents with `_from` and `_to` attributes.

So whatever representation your graph comes in, you need to break it down to this.

I'm using arangoDB tinkerpop-provider in JAVA. If I load the collections with arangoimp, it would be a collection in the database without attached to a general graph in arangoDB graph module. So that I could not use a graph name to cite these collections together. 

To be more specific, if I use arangoimp, I would do something like this:

arangoimport --file "data.jsonl" --type jsonl --collection users --server.database "myDB"

This command would load the users collection into "myDB". Whereas in graph module under arangosh, I would operate a graph like this:

arangosh> var graph_module = require("@arangodb/general-graph");
arangosh> var graph = graph_module._create("myGraph");
arangosh> graph._addVertexCollection("shop");

Or this to load a existing graph:

arangosh> graph = graph_module._graph("social");

Also, in tinkerpop java provider I need to provide a graph name to indicate a general graph:

ArangoDBConfigurationBuilder builder = new ArangoDBConfigurationBuilder();
builder.graph("modern").arangoUser("username").arangoPassword("password").
       withEdgeCollection("e").withVertexCollection("v").configureEdge("e", "v", "v");
Graph graph = GraphFactory.open(builder.build());

So the main gap between use collections and graph module is the graph name part. 

I wonder if there is some way to transfer a set of collections to a graph so that I could operate in graph module or some other ways.

Hi,

You can still use a named graph that spans these collections.

However, feeding it via document operations means that you have to maintain the integrity of the graph - i.e. not to create dangling edges.
