The problem is that there are no cypher commands currently but core-api
calls.
and it is reading and writing, so you would have convert all of those into
cypher statemetns and send them over the wire which would be probably even
slower
You could probably hold off sending the http request until you
Using Neo4j without relationships is not what you would use a graph
database for. You _should_ create meaningful relationships between your
nodes.
I don't see where the example you mentioned misses relationships?
If you have a simple text file (csv) with your relationships, you can
easily create
Hi,
Yes this more lika general web development question, but i would recommend
a memory store rather than a disk based solution for sessions (i.e
redis,memory,memcache etc). Almost everthing *can* fit into a graph but it
is a cost to be made if you want everything on disk and you also need to

I do not need to know how many label can have a node.
I need to know how many label i can create on the graph.
Actualy my graph use many tables and i would like to create a Label for
each tables, or columns.
Why i did that!
Because of the lake of more precises examples (

Hi,
I know my question is very generic but do you think neo4j is adequate
solution to host a full web application that needs user profiles, sessions,
user relationships,items inventories etc or should it be complemented with
mongo?
thanks

I think it is 16 bit, i.e. 64k
Why do you want to know that?
Up to 5 or 7 labels can be stored in the node as long as their id's are
small enough. (fitting in 5 bytes).

Split it up in one more intermediate step, the intermediate steps are there
to get the cardinality down, so it doesn't have to match billions of paths,
only millions or 100k

Please help me again Michael.
You ever said:
I would also change:
MATCH (U:User)-[F:Friend]->(FU:User)-[FF:Friend]->(FFU:User)
WHERE U.user_id=1 AND FFU.user_id<>U.user_id AND NOT (U)-[:Friend]->(FFU)
RETURN FFU.username
to
MATCH (U:User)-[F:Friend]->(FU:User)-[FF:Friend]->(FFU:User)
WHERE U.u

Could it be that the constraint was not yet online when you tried to drop
it? I.e. it was still building?
It seems lucene was still writing to the backing files.

Something went wrong there.
Can you share your graph.db/messages.log file to see if we can find out the
reason?
Your create/drop constraint syntax is correct.
