Re: [Neo] Communication channel preferences?

Re: [Neo] Persistance of nodeID
I don't know if this is best practice but I have in the passed used
the ref node to store stats about the graph, I.e. Node count,
relationship count etc

Aditionnaly, i think that i found the easiest way to know if i run a
new database for the first time :
if(referenceNode.hasRelationship() == false) {
//we are running this database for the first time
//initialize stuff.
}
Sounds like an excellent idea.
Just a thought: when I write code with neo4j I never think of an
initialization phase, but rather that my nodes and relationships are
always created on demand as needed if they don't exist. Maybe that's a
matter of taste though.

Thank you for your very fast replies.
I will have more question, soon.
But it's time to eat and i'll have some code to do before jumping
to
the next problem.

Re: [Neo] Api - setProperties(Map properties) ?
Obviously thats what I've done :) I just kinda thought that maybe a constructor that took a Map was the one thing I might like in an otherwise lovely and simple api...

Re: [Neo] New features in trunk
Johan, your my hero! The readonly mode stuff is going to be a god sent to us and the depth traversal stuff is definitely going to help some of our longer jobs. We have a deadline to hit next wednesday but straight after I'll get testing it on out bigger graphs. Thank you... Dan On Wed, Sep 2, 2009 at 2:16 PM, Johan Svensson jo...@neotechnology.comwrote: Hello, Now that the 1.0-b9 release has been out for a while we have had some time to work on some important new features that we want to be part of the final 1.0 release. The 1.0-b10-SNAPSHOT (trunk) now includes: o New algorithm to rebuild id generators during recovery after a crash. Cuts recovery time on large stores to a fraction of the time it used to take. o Read-only mode. You can now startup multiple read-only NeoServices to the same store (using EmbbededReadOnlyNeo) and have a single writer to that store. o Improved depth first traversal speed on nodes with many relationships by loading relationships on demand. This will also reduce the stress on GC when traversing over a node with many relationships since much fewer objects will be created. If you have some suitable project please help us test and try out these new features.
