Re: [orientdb] how many graphs

2014-01-08 Thread Andrey Lomakin
Hi Alan, You can create as many graphs as you need in single Graph instance. It is better than create 3000 graph databases because in case of single storage you will have much efficient RAM usage than in case of 3000 storages. You can tune RAM consumed by memory storage using storage.diskCache.buf

Hi Alan, Another benefit of having several graphs is that you can easily move some to another server to balance load on servers. But clearly, there is a restriction, you can't easily implement connections between this graphs (e.g. edge from graph A to graph B). Will a running server detect new g

Hi, I suggest you to use the Blueprints API, specially if you don't have properties on edges: edges will be created as "lightweight" and this is much faster. Lvc@ On 8 January 2014 10:09, Pawan Goyal wrote: > Please find the file in the attachment. > > I use case is no duplicate node ,edge sh

Could you explain what you mean by partitioning the data. It's not clear to me what you mean. So far my use case is this. 1. I'll have a single server instance (@port 2480) which only serves read-only queries for 3000 graphs. e.g. server.database.path = /opt/orientdb/database
