Re: [Neo4j] Multiple relationship of same type between two nodes

Ok. I figured that we need to specifically allow duplicate relations and a few alternate ways to fetch all the relations. I am using spring SDN. The API's are not very intuitive. Regards, On Thursday, January 23, 2014 1:19:00 PM UTC+5:30, Michael Hunger wrote: > > Yep thats perfectly fine > > Se

Re: [Neo4j] Re: Optimising thy cypher queries

I haven't tested performance of UNION much. It's hard to do any sort of aggregation over the whole query which makes it a bit harder to use than WITH in some situations. Hope they add some syntax for that sort of aggregation at some point--seems like UNION could be parallelized more easily. Wes O

[Neo4j] Re: Optimising thy cypher queries

I've know that one of the ways to kind of join queries is by using WITH and specifying which identifiers you wish to 'pass on' to the subsequent part of the query. My question is, I've recently come across the UNION statement. How different is it from WITH in terms of performance particularly f

Just do the calc, its not that many nodes: only 525k and you can create them on demand, so only for minutes / hours that actually have events. On Thu, Jan 23, 2014 at 8:31 PM, Javad Karabi wrote: > define "heavy". > heavy sounds like you are worried that there would be alot of nodes in the > gr

[Neo4j] Re: Return all events that occurred between two dates.

define "heavy". heavy sounds like you are worried that there would be alot of nodes in the graph. there would be, i imagine, but with neo4j being a graph database, the number of nodes increasing does not degrade performance. MERGE (y:Year {year: {year} }) CREATE UNIQUE y-[:month]>(m:Month {month

Re: [Neo4j] Embedded HIghlyAvailableGraphDatabase - database path

Kalidhakani, Your embedded instance will not be allowed to touch the files belonging to those 3 instances that are already running the cluster. Instead, you have to make your embedded instance join the cluster as the 4th member, with it's own copy of the database (e.g. /home/myData4/graph.db ).
