Dougal Watt commented on ATLAS-1757:
------------------------------------
The state of integration for graph DB's is somewhat in flux, with Tinkerpop
being more oriented towards analytics use cases than straight out integration.
For the latter, GraphQL is proving to be a very nice solution (graphql.org).
It's a query language and information-centric API rolled into one, and both the
query syntax and outputs are structured in the same way. Nicely, the query
return is in JSON format, so everything on the upstream side of the API can be
totally standard internet technologies. The architecture of GraphQL also allows
for integration of any back end data store so you can have more than one,
pluggable databases behind the scenes.
I've started two companies building SaaS products on top of graph DB's, and
choose Blazegraph due to it's support for RDF and GPU acceleration. An RDF
graph would allow Atlas to define the required metamodel in RDF and use it to
reason over instance data received and send by Atlas between different data
lakes - you'd also get metamodel validation and conformance, and a highly
evolvable schema.

> Project: Atlas
> Issue Type: Improvement
> Components: atlas-core
> Affects Versions: trunk
> Reporter: Graham Wallis
> Attachments: ATLAS-1757 Proposal to change graph database.pdf
>
>
> Given the formation of the JanusGraph open source project (under the Linux
> Foundation) to continue the development and support of the Titan DB, should
> we aim to deprecate Titan and move over to JanusGraph?
> If we did this, we could keep the graph abstraction layer and use it to
> support Titan 0, Titan 1 and JanusGraph.
> Are there other graph databases that we should consider?
