> I'd like to work on supporting [Accumulo|http://accumulo.apache.org] as well as HBase as a persistent store for the code in org.apache.atlas.repository.
> I can see two ways that this could work:
> # Define a new GraphProvider and provide an implementation of the Tinkerpop blueprints Graph which is backed by Accumulo - there are several good options here like [Calrissian|https://github.com/calrissian/accumulo-recipes/tree/master/store/graph-store] or the [JHU APL implementation|https://github.com/JHUAPL/AccumuloGraph].
> # Implement a new [Titan storage backend|https://github.com/thinkaurelius/titan/wiki/Storage-Backend-Overview] that writes to Accumulo. Any changes to Atlas should be limited to Titan configuration (probably some Accumulo-specific parameters).
> Would this improvement be welcome? If so, can somebody suggest the best way to proceed? I was looking at option #1 originally but it looks like some parts of the code (eg. [GraphBackedMetadataRepository|https://github.com/apache/incubator-atlas/blob/6b33bcf647264131cf5b37838485675d2ed9c017/repository/src/main/java/org/apache/atlas/repository/graph/GraphBackedMetadataRepository.java#L87] have explicit dependencies on TitanGraph, not the Tinkerpop Graph interface.
