Subject Re: Titan: configuration in atlas
Date Sat, 05 Sep 2015 01:27:40 GMT
Nigel,

Atlas has sufficient abstraction over the repository and does not want to
expose it to the users. Given that we have a type-specific DSL, we would
like users to interact with the system using that or full-text search.

Rester read-only API was added for testing and I purposefully left out the
server part since it allows mutations.

Given that you want to poke around a graph db, I'd suggest you download
titan server with rexster and just point it to the atlas db dir.

Makes sense?
