Yes, babudb would for example be very fast for a primary key index. How do you think a trie implemented in neo4j would compare to the others? One could have relationship types for each letter. Then a search for the word "faster", would involve six Node.getRelationShip(RelationshipType,Direction) c

I have given the information about the benchmark to the babudb guys. Hopefully we will have a performance war coming up. atle On Tue, Jun 15, 2010 at 10:50 AM, Mattias Persson wrote: > 2010/6/11 Atle Prange : >> Regarding the performance: >> >> I have tried to tweak Babudb, but could not get any

Regarding the performance: I have tried to tweak Babudb, but could not get any more out of it than you did. I guess when you put 5M entries at once, there is only so much tweaking one can do. (At least for babudb). It seems odd though, since babudb is a less complicated framework, with less featur

I tried performance of BabuDB recently. I'm not very used to key-value stores, but I chose this layout of the keys/values: key: key|value|id value: id I chose this layout since there can be many nodes (ids) indexed for each given key/value pair. Now, I found the insertion performance to be
