> Tinkerpop3 - graph store abstraction
> ------------------------------------
>
> Key: ATLAS-518
> URL: https://issues.apache.org/jira/browse/ATLAS-518
> Project: Atlas
> Issue Type: Wish
> Affects Versions: trunk
> Reporter: Nigel Jones
>
> Atlas is currently based on tinkerpop2 & titan 0.5.4. Work is needed to bring
> it up to the current tinkerpop3 level which would be covered by any titan
> upgrade as mentioned in ATLAS-517.
> However one role of the very active tinkerpop project is to provide a layer
> of abstraction between a graph data store, and applications (such as Atlas)
> (See http://tinkerpop.apache.org/docs/3.1.1-incubating/reference/ )
> By adopting tinkerpop interfaces where possible we can facilitate
> integration/interop with other graph stores and offer much more flexibility
> in implementation as appropriate.
> Tinkerpop (or gremlin as the term is now used for the whole stack) isn't
> complete -- for example creation of indices today relies on defining the
> index in the underlying implementation (in our case titan), but we also have
> the opportunity to work together with the tinkerpop team to reduce these
> interdependencies moving forward
> From a scan of the code Atlas today uses titan APIs and it would require some
> effort to migrate. This JIRA is being opened to get discussion on whether
> this direction makes sense, to understand the pros/cons of such an approach,
> and to evaluate the impact/feasibility of making such a change.
