Re: [Neo4j] logical logs

When keep_logical_logs is false, it will delete the just-rotated-out log file after a rotation, so yeah, it’ll leave even older ones alone if any. Since 2.2.0, the index commands are part of the normal transaction log. Before 2.2.0, the Lucene index logs were separate but used the same keep_logi

[Neo4j] Neo4j Server Ready & Running Status Code??

Hi, I have to monitor if Neo4j is ready and is up and running. I understand that there are some REST status codes. Is there a status code and/or method for querying the status of Neo4j? I think there is a "neo4j status" command. However, I do not necessarily want to launch a shell to execute

There is no "map-reduce" out of the box, but you can develop concurrent pretty easily. My colleague Max started a project around this: https://github.com/maxdemarzi/graph_processing Where you can find implementations for some algorithms using c

Hello, I am running 2.2.1 enterprise. I changed the keep_logical_logs setting of the DB to false (in development). However, I still see old neostore.transaction.db.xx files. Is this simply because neo isn’t cleaning the old files now that the new setting has been applied? Am I ok to delete those

Thank you for the reply Michael. I have just published the issue. I was using as usual -Xmx4g. Now I've just tried with 6GB and open and close a single transaction for every query like that on the different indexes and I do not get this exception. So now it has more need of memory for the same o

[Neo4j] Using Neo4j + MapReduce

Hello, Is there a way to run parallel graph algorithms using map-reduce paradigm on a graph represented in Neo4j. Like if I wish to run a map-reduce version of Bron-Kerbosch algorithm to enumerate all maximal cliques in a graph represented in Neo4j, is there a way? Please provide some pointers

Re: [Neo4j] Neo4j modeling : better keep data unique and linked or duplicate it ?

I think it depends on the use-case if your use-cases and queries make use of that structure to provide some functionality that is hard to achieve otherwise, then go for the graph structure. If it is just for the storage and some property lookup or comparison it might not be worth it. There is

Not sure what your experience is, but you can use a JDBC driver to work with Cypher both in embedded as well as remote mode. see http://neo4j.com/developer/java There are example projects and more details Cheers, Michael > Am 16.04.2015 um 12:22 schrieb sohail
