How would I go about getting all relationships in the entire database ?
(with neo4j embedded)
I see there is an db.getAllNodes() for nodes
is there something similar for relationships?

Hey Jim,
I am sort of glad to hear that, maybe in the future I could see a method
like getAllRelationships(), or not, np :)
Yes, using Michael's code works, but ...
total relations count=100,011 timedelta=3,075,897,991 ns
it kind of takes 3 seconds (when not cached) to count 100k relationships

implementation would be probably faster.
If timing is that critical for you, you can have a look in
EmbeddedGraphDbImpl.getAllNodes() and implement a similar solution for
relationships.

nice, no errors now, thanks! I've been postponing checking stuff like

Hi xD
I'm not clear what you need to store here, if I understand correctly you
could store in 2 primary bdb databases the nodeID (ie. long) of each node in
a relationship
ie.
key-value
dbForward:
A-B
A-C
X-D
X-B
dbBackward:
B-A
B-X
C-A
D-X
A,B,C,D,X are all nodeIDs ie. longs
this way you could
Hey Niels,
As they are composable, is java going to keep track of things, like if
