Daniel Kuppitz commented on TINKERPOP3-479:
-------------------------------------------
Others may not know what you're talking about.
here's the BulkLoader:
https://github.com/apache/incubator-tinkerpop/tree/blvp/gremlin-core/src/main/java/org/apache/tinkerpop/gremlin/process/computer/bulkloading
It's work in progress and thus subject to a few more refactorings. But the key
part is an interface with methods like this:
{code}
Vertex getOrCreateVertex(final Vertex vertex, final Graph graph, final
GraphTraversalSource g)
{code}
> Consider Providing "getOrCreate" Functionality

> Key: TINKERPOP3-479
> URL: https://issues.apache.org/jira/browse/TINKERPOP3-479
> Project: TinkerPop 3
> Issue Type: Improvement
> Components: structure
> Affects Versions: 3.0.0-incubating
> Reporter: stephen mallette
> Fix For: 3.1.0-incubating
>
>
> One of the most commonly written functions used is good ol' "getOrCreate"
> where you want to get a {{Vertex}} if it exists or create it with supplied
> properties if it does not. We currently have a "helper" function for this on
> {{ElementHelper}}
> https://github.com/tinkerpop/tinkerpop3/blob/6d0f00865f673cb0739f6f310e1868425f732924/gremlin-core/src/main/java/com/tinkerpop/gremlin/structure/util/ElementHelper.java#L62
> but perhaps it is time to treat this issue as a first class citizen as part
> of the Graph API. I think that some vendors might actually be able to
> optimize this function as well.
> Another aspect of "getOrCreate" is "upsert" as well as options to ensure
> uniqueness. All of these things we've at some point or another built
> variations of outside of TinkerPop for applications, data loading, etc.
