Thank you:) Could you tell me what about aggregation? Does OrientDB provide any function to choose a subset of edges (with specyfic property) and make fast addition for another property of edges in this set, or property of vertexes in the set of pointed vertex. I mean something like an equiv

Hi, We have costumer in production which has 700 000 edges for one vertex and does not experience performance problems so that is what graph databases are intended for. On Thu, Feb 6, 2014 at 9:24 AM, Tomek Kulakow wrote: > Does it make sense to create a graph with a very large amount edges > b

2014-02-06 Thread Tomek Kulakow
Does it make sense to create a graph with a very large amount edges between vertices? For example if I have sellers and products as vertices and each net user by buying something adding new edge (a edge from a seller to a product with data and amount properties means that a seller sold a produ
