Subject Architecture questions - Falcon's knowledge of feed instances
Date Thu, 23 Apr 2015 19:42:06 GMT
Hi,
Wanted to verify a few things and ask a couple of questions...
Chasing through the code a bit, it looks like Falcon stores information about feed instances
in a graph DB, using TinkerPop. From the configs, it looks like TinkerPop is on top of BerkeleyJE.
Is that correct? Is it running as an in-memory database that gets loaded at startup or as
a persistent store that is queried as information is needed?
Is information about instances stored anywhere else? That is, when you use the API to list
he instances of a feed, does it get that information from the graph DB?
What information does it store about an instance? scot, is the instance represented as an
object with a pre-defined structure or is it a graph node to which properties are attached? 
Is any of this documented anywhere? Is this what the "Falcon config store / Graph" in the
Architecture diagram refers to?
thanks,scott
