Hi Linan,
These are good questions. I am currently following a similar approach to
characterizing the performance of basic graph operations, and then also simple
graph algorithms on various "shapes" of graphs. My initial investigation is on
small graphs on my laptop, but this weekend I'm testin
hi,
I once read a blog about how long it take for computation operations
such as read from L1 cache, RAM access, send packet from usa to eu,
etc. having a rough idea of the relative cost of major computation
operations, we have better control. for example, in my project i also

Hi folks,
just commited some example code to show the use of
Uniqueness.NODE_PATH in the Neo4j traversal framework in order to
return paths that share nodes.

Enjoy!

Linan,
yes, deep down Pipes are composing the pipeline out of iterators to
the base API operations node.getRelationships() and
relationship.getNodes() . The Neo4j traversal API is using callbacks
instead. What you want to use depends on your taste :)

Actually i'm fine with nesting multiple traversers to solve the
problem if deep inside gremlin, evaluator and fluentPipeline are just
nice constructs over the same solution. is it correct?
thanks

this can well be a packaging problem. Could you try with 1.5.M01? The
dependency problem is fixed, but we are fighting for the build

Yup,
Don't upgrade dependencies right now before Gremlin 1.3 is out and can be
tested with the Neo4j QA.

Could you also describe the graph you're using or provide a generator and your
cypher query.
We can use that in the future for performance optimizations.

Marko,
in principle, you can without much overhead. Be aware that you will

are not, either. So, try it out, but remember - you have push rights

I'd gladly put out a piece of code demonstrating the use of IndexRelationships,
using this "LIVES_IN" example. Though I get the impression the question here
relates to the normal relationship index. However when "supernodes" (still
don't like that term for densely connected nodes) come

Could you share the content of the mesages.log file in the database directory ?
Also do you sometimes kill the neo4j instance abruptly with kill -9 or similar
? That can cause corruptions of some lucene files ?

Spring Data Graph stores the type information in the graph.
The default is to use indexes to store this information, but it can also be
stored as type-nodes with relationships to all instances.
The current neoclipse supports index lookups, so please try the following:
the index name is: __types
again the same error...
any idea?

I'm using spring data to persist my data. And so far I was able to both
