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
Hi,You basically have two options. If your result set is not too big, you can
sort it in memory, though that approach may consume too much memory if the
result set is very large. In that case you can use SortedTree (see:
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
Well in fact, I expect to order the resulting set of nodes by a property on
that end nodes. But This class cold also help on some use cases I think.

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.

Jajajaja, Marko I just need to meet you sometime! I always listen good thing
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!
