David Radley commented on ATLAS-1757:
-------------------------------------

[~hulbs] The equivalent to the RDB grant is all done through Ranger - which 
gives us great separation of responsibility and flexibility.  I have no reason 
to think that Apache Ranger mechanism is not strong enough for the use cases we 
have looked at.   

If the data really needs to be separate - and does not need to be joined, then 
it might make sense to have them in separate data lakes - i.e. separate 
Atlas's.

> 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?
