Re: [Neo4j] Could kapsack problem be solved via graph traversal using bounderies?

Hi Lundin, sorry didn't have time to look into this. Perhaps when you're in Malmö you can chat directly with one of our engineers. Otherwise let's find a time to talk about it. Cheers, Michael Am 03.04.2014 um 04:13 schrieb Lundin : > I am sorry but so no one knows if "run sums" is possible

Re: [Neo4j] CREATE INDEX and deadlock.

Index updates grab a schema lock, so you might be seeing this. But as Mike said, you should be able to run them all in the same tx? Indexes are populated asynchronously anyway. Only constraints are sync afaik. Michael Am 08.04.2014 um 23:20 schrieb Mike Holdsworth : > If you create the indexes

Re: [Neo4j] CREATE INDEX and deadlock.

If you create the indexes synchronously, or as a single batch in an async handler, does it work? In my Spring app, I can perform multiple schema ops in the same transaction, but running them independently with @Async I experienced deadlocks as separate transactions are started for each thread.

Re: [Neo4j] CREATE INDEX and deadlock.

Here is the code that creates the indexes that runs into a deadlock (typically on the creation of the index for the Folder label): function buildIndexes(data, callback) { var catalogIndex = false; var q = async.queue(function(item, queueCallback) { db.query(item, null, function(err, results) { if

[Neo4j] How to nest a query with Neo4j?

I am trying to do a sort of nested Neo4j query in Java, which first labels a subset of nodes and then tries to match certain patterns among them. More specifically it is like combining 2 queries of this type: 1 - MATCH (n)-[r:RELATIONSHIP*1..3]->(m) set m:LABEL 2 - MATCH (p:LABEL)-[r2:RELATIO

Re: [Neo4j] CREATE INDEX and deadlock.

I create several indexes/constraints in the same transaction all the time. Can you provide code examples to reproduce this issue? I have a feeling you may be creating conflicting indexes (indexes on the same label/property), or something. If not, maybe it's just that they're running in separate tra

[Neo4j] CREATE INDEX and deadlock.

I am noticing that if I try to do more than one CREATE INDEX at the 'same time' I run into a deadlock exception. But before you say 'don't do that', which is the natural response I would like to know why. Is the process of creating an index essentially locking the database and should always be

Re: [Neo4j] Roadmap for label + relationship type removal

The label legend in the graph viz should be fixed now, the labels in the overview tab on the left side stay, that's true. I think Andreas who answered on the SO post is the best person to clarify this in terms of roadmap. Good point raising it, I'm not sure it will be a priority in the near future

You mean removing the label-id's and rel-type-id's in the database? Afaik it's not on the roadmap so far to cater for their total removal? So far it has not really been an issue. What makes you ask the question? If it is really critically needed you can make a store-copy and leave of the labels or

Hi, so far I investigated that label and relationship type removal is not possible right now, or? - see, e.g., http://stackoverflow.com/questions/21983425/how-to-delete-labels-in-neo4j i.e., the only and not so comfortable way is to clean-up the data directory in $NEO4J_HOME (which results in a
