[Neo4j] Server sizing for log-storage

Hi List, I'm currently investigating how we can improve our storage of our website's pageviews. The model described in the wiki seems to be be a bit too simple for our case, but is basically how I'd like to do it. We serve about 1 billion pageviews yearly, so that's already 3 billion

[Neo4j] Recommendation based on likes

Re: [Neo4j] Question about labelling all connected components

One other option is to have a set of nodes, each of which represents a component. You can create a relationships of type OWNS (or whatever) to each of the nodes of a given component. This makes component lookup rather simple (just grab the node that represents the component, then traverse all of

Re: [Neo4j] Batch inserter shutdown taking forever

2010/7/21 Tim Jones bogol...@ymail.com Hi, I'm using a BatchInserter and a LuceneIndexBatchInserter to insert 5m nodes and 5m relationships into a graph in one go. The insertion seems to work, but shutting down takes forever - it's been 2 hours now. At first, the JVM gave me garbage

[Neo4j] Rest Api, How to access relationship property inside return filter?
