[Neo4j] Explicit transaction context

Is there a way to get a hold of the transaction context, and pass it around, instead of having it bound to a thread. The case is that i want to use actors for multithreading, and the transaction might leave the thread it was started in. -atle ___ Neo4j

Re: [Neo4j] distributed neo4j

Hmmm, I'll check out the paper, but I think the problem with any shared memory is to maintain consistency you have to synchronize and that will drastically reduce scale. I think eventually consistent, share nothing graph stores with merging/replication (master/master) is the way to go. Ilya On T

Re: [Neo4j] distributed neo4j

The paper looks interesting, but could you perhaps give me an outline of the differences between distributed key-value stores (like www.hazelcast.com), and distributed shared memory? -atle On Tue, Sep 7, 2010 at 12:01 PM, Jim Webber wrote: > Hi Atle, > > I'm thinking along different lines: som

Re: [Neo4j] distributed neo4j

Hi Atle, I'm thinking along different lines: something like distributed shared memory with caching (and performant cache invalidation). My old friend Savas Parastatidis implemented such a scheme around 10 years ago for his PhD, and I'm starting to think whether it'd be an appropriate approach f

Re: [Neo4j] list or tree ?

Hey Stephane, It occurs to me that a general strategy for improving traversal speeds is to add indexing nodes that help reduce the number of possible paths to check. For instance, you could add "week of the year" nodes which group bank receipts and statements into a time-oriented groups. In the at

Re: [Neo4j] distributed neo4j

Hi, i have been thinking about this for a while, but i am not very smart, so the results aren't that interesting. One way to solve this is just to model the graph ontop of a key-value store, and store pointers to nodes and relationships in the values. The pro is that its easy to implement, and it
