Is there a method or suggested approach for obtaining a list of all of the

I agree with David's suggestion of using relationship types for two reasons:
- It definitely makes querying/traversal easier
- It reduces the need for unnecessary properties on a "generic" relationship
type (the relationship type's .name() method provides something like an
"implicit" property)

I definitely understand the reason for wanting to use Git, with the more
frequent forks and branches of late, but I do think it would be helpful to
make snapshot builds *with source* available for download as ZIPs or TARs as
well. For those of us on Windows, there are practical limitations to how
Maybe this is a stupid question (or not), but I'm assuming that the
relationship id will also be expanded as well? Supporting a large # of
nodes without also supporting a large # of relationships would obviously not
make sense, but just wanted to confirm.
Thanks,

Awesome stuff. Do you have any examples of Pipes being used in a non-graph
scenario? I'm considering using it as a possible foundation for a complex
event processing (CEP) engine. It looks generic enough that it could be
extended/applied in that way. LMK your thoughts.

, I
think looking into wrapping eventually consistent datasources and
graph based datasources would alsobe a good activity leading up to
your scenario.
Let's talk more about how this could look in practice. Got any example
code running yet?

Is there any advantage/difference of using one or the other?

Hi, all.
Since it has been a frequent topic of conversation recently, I'd like to get
a roadmap dialog started on the topic of a companion blob/document store for
Neo. While there are plenty of ways to "roll our own", it requires a lot of
extra effort when we get into HA and load balanced scenari
Axel, are you storing the actual content in Neo or in the file system
directly (or some other datastore)? I've been told not to use Neo for
blob/large text storage. Curious what approach you're taking.
Best,
Rick

If I have a string property on a node, and I overwrite it with a new value,
it *appears* that the disk space for the previous value is still allocated
in the neostore.propertystore.db.strings file. I say this because the value
happens to be rather large (about 2MB), and after a few writes, I notic
So the issue was in Neo and not Neoclipse? If so, is this a recommended
patch for everyone running Neo 1.2 who might encounter a recovery/restart
situation, or is this something specific to a Neoclipse issue?
Thanks,

Out of curiosity, has anyone looked at re-doing the rendering engine of this
in SVG? Now that SVG will be officially supported in IE9, its practicality
for web apps is much more substantial. Issues like hit testing/item
addressability/animation, conditional display based on zoom level, and other

Tied in with my SVG question (which should be posted shortly), you can move
some of the UI rendering to the server as well, and with SVG you could
cleanly integrate data + UI elements in what is sent back to the browser. I
think a mix of browser smarts to control client-side rendering (zoom levels
Don't forget that Neo4J can also run as an embedded graph database, where it
is SUBSTANTIALLY more performant and much more flexible to utilize than via
the REST API.
