Having used (and moved off of) Titan I do not recommend it as a primary database. Until it overcomes it’s extremely unoptimized graph traversals, it will increase the load on your database by several orders of magnitude.
As a secondary analytics database, it might do fine. Just don’t rely on it for anything time sensitive. Jon On Nov 16, 2013, at 9:10 PM, Willie Slepecki <scpha...@gmail.com> wrote: > Hi all.
