Hi, I am trying to figure out a way to create random unique edges in the
graph. I have written the following query to create a relationship between
two users, but count always return 1 whether a new relationship is created
or not.
Is there a way to determine whether there was an existing edge
Just found out that I was storing the graphDb in another class and I did
not update the reference to it. Sorry for spamming.
Kind regards,

Any idea why the database is still shutdown instead of restarted? Thanks.

Hi,
I have seen a few questions that were posted from before that it does not
free the space up immediately. My application is running analysis over the
database repeatedly but each time inserting different number of
relationships so I have to remove them before I run the next iteration. The
I am trying to find an efficient way of traversing all nodes and find
transitive relationships of length 2 on my database. Currently, I am using
query1 to compute the new properties for the new relationship and query 2
to add the relationship into the database
query1:
MATCH (a:USERS) -
Hi,
I am wondering is there a way to create a unique relationship from nodeA to
nodeB using just the java api? Or must I execute a cypher query for that?
Also, if both ways are available, which way is more efficient? Thanks.

I am trying to iterate through the results from the first query and execute
an extra cypher query for each result to either create or find the existing
relationship. However I encountered GC overhead error and the stack trace
is as followed. I thought running the queries in batch of 100 will
Hi,
I am looking into storing twitter data into graph database for some
relation analysis. I am hoping to use neo4j but I am a bit lost as to how
to start using it in my java application.
I have read online that it's easier to use spring but I have not used
spring at all before.
I found two
