HI!
I am on the situation of having to traverse neo4j, and then expect the
resultset returned to be ordered in a certain order. I've been researching a
bit over the traversal API, but I did not find anything related to that. I
really will appreciate any tip on that!!
BTW I expect to be possible
Hi Pere,
To sort you need to have all your results.
Thus, in Gremlin (and hopefully you can do the mapping to the core Neo4j
traverser framework),
results = []
g.v(1).out('friend').out('likes') results // what my friends like
results.sort{a,b - a.name = b.name} // sort resultant vertices by
/java/org/neo4j/collections/sortedtree).
This allows you to layout the relationships you want to traverse in sorted
order.

Well, this is great if I want to do all the math in memory, but I expect to
do the computation by the db.

Hi,
Ah. Then I would recommend using a persistent data structure such as the one
the Neil discussed in his follow up post.

Well the graph structure is not relevant here, I think. The property I
expect to be sorting is on the destination node, so
the relationships you want to traverse in sorted
order.

Well the graph structure is not relevant here, I think. The property I
expect to be sorting is on the destination node, so I can do the traversal
and then expect to run the sorting.
Please, tell me how the data structure can help me to deal with that order

Well, the thing is that the database can easy deal with that, as the

Hey,
Isn't that pretty similar to what
https://github.com/peterneubauer/graph-collectionshttps://github.com/peterneubauer/graph-collections/tree/master/src/main/java/org/neo4j/collections/sortedtree
provides
for Neo4j?
I dunno. I haven't played with Graph Collections. But I assume so if it
handle it.

about you from Peter and Achim ... I am quite not satisfied, probably I will
change somethings on my project in order to fit better with that use case!
