Thank you Andrey. Look forward to the changes are they in 1.7 SNAPSHOT already? It's good to know about the ~50 links and the separate data structure.
Can I force the system to use the separate data structure after insert? (The reason I ask is that if I can then I can use oversize=0 and rely on the external structure for the few vertexes that will require new edges) Regards, -Stefán On Friday, 24 January 2014 11:57:02 UTC, Andrey Lomakin wrote: > > Stefan, > We are going to release first version of implementation of new relations > in graphdb which is sometimes 20x (that is true) times faster than current > one. > Aslo data structure is used in this relations was tested by Kai Londenberg > and he confirmed > https://groups.google.com/forum/#!searchin/orient-database/sbtreebansai/orient-database/ltNElAF0H_o/uQOwqAliUH8Jthat > even on millions of relations there is no performance degradation. > > I attached also early benchmarks, that is benchmark of import or Wikipedia > data in OrientDB. > > Firs line amount of records, second line time spent for insertion of 100 > 000 records. > > Full benchmark which we will run during 12 hours will be published at > Monday (ridbag is new impl ridset is old impl). > > > About your question in case of more than 50 links (roughly speaking) these > links are stored in separate data structure so you should not worry about > oversize. > > > On Fri, Jan 24, 2014 at 1:21 PM, <[email protected] > <javascript:>>wrote: > >> Hi, >> >> I have a potential use case where I have a very high number of edges >> (millions) for a document and I'm wondering if I should change them to >> one-directional links from the other site. >> >> Is there a practical limit to the number of edges for a vertex?
