Hi,

I am using Neo4j for my travel database where every location is a node and
hotels, restaurants are child nodes of location nodes. Right now number of
nodes is less but later own it will easily cross a hundred thousand nodes.
So my question is

1) Has any body been using Neo4j with more than a hundred thousand nodes in
production environment, if yes what kind of optimizations from modelling
perspective they had to do?

2) If number of nodes is an important factor in performance and scalability
than should we model such as to keep the nodes to minimum.

Thanks in advance!

Based on my limited experience so far, it seems like the biggest things are:
- having enough RAM (where enough depends largely on the kinds of things
you are doing)
- keeping your queries local and limit the start points to a reasonable
number (don't do start n=node(*) match n-[r*]-m return n, m; and expect it
to finish in this century with a big graph)

Wes
