Re: [Neo4j] Id capacity exceeded
Alfredas, AFAIK there is a limit on the number of Relationship types is max 32000 in the cache layer, a bit higher in the storage layer. Mattias has been doing a branch for more in order to support Rene Pickhard in his Activity Stream algo that uses types heavily, see http://www.rene-pickhardt.de/data-structure-for-social-news-streams-on-graph-data-bases/ but that is not in master. So, I think a property on the relationships is a better way to go right now. Also updated the docs to reflect this, see https://github.com/neo4j/manual/commit/796ef8d2e3bf99df7410f53e37860296e6b616c6 Cheers, /peter neubauer GTalk: neubauer.peter Skype peter.neubauer Phone +46 704 106975 LinkedIn http://www.linkedin.com/in/neubauer Twitter http://twitter.com/peterneubauer brew install neo4j neo4j start heroku addons:add neo4j On Tue, Nov 29, 2011 at 6:58 PM, Alfredas Chmieliauskas alfredas...@gmail.com wrote: Dear all, after creating some relations i get the error org.neo4j.kernel.impl.nioneo.store.UnderlyingStorageException: Id capacity exceeded See trace below.

Re: [Neo4j] Id capacity exceeded
Thanks Peter. I got it to work with relationship properties. I am pretty sure that the number of different relationships I was trying to create was less than 32K. Maybe its a good idea to test that limit..
