Marko A. Rodriguez updated TINKERPOP3-570:
------------------------------------------
Description:
I'm trying to figure out how we can, within a "single traversal", move between
OLAP and OLTP at different sections of the traversal. E.g.
{code}
[g.V.out.has('age',lt,25)]OLAP[out('parent').out('workPlace')]OLTP[out('coworkers').age.groupCount]OLAP
{code}
Going from OLAP to OLTP is easy. We have solved that already as OLAP queries
return a {{Traversal<S,E>}} and thus, can be further processed in OLTP. But
what about going from OLTP back into OLAP? We need to be able to stream the
OLTP results back into traversers on the vertices of the graph -- TinkerGraph
(easy), Hadoop (dynamic editing of the disk format!? crazy) .. is there a
general pattern that works for all graphs? Finally, what about when the objects
are NOT vertices/edges/etc. See the next issue.
