Re: [Neo4j] SpringDataNeo4j 2.0 Supernode navigation

2012-01-16 Thread Mattias Persson
With this branch you have expected getRelationships time regardless of how
many other relationships that node also has got, since only the
relationships that you request are loaded (based on type and direction).
You can also get an accurate relationship count (even for a given
relationship type and direction) as an O(1) operation.

 Agelos,
 supernode support for these cases will be handled below SDN. Mattias
 has been spiking this in
 https://github.com/neo4j/community/tree/super-node-support but we have
 had no time to merge this in, since the QA on store changes is
 non-trivial.

 Cheers,
