Re: [Neo4j] neo4j upgrade, loss of data!

This could be a browser issue actually. I tried running your query directly via a Cypher ExecutionEngine, and no matter how many times I tried, it always gave me the 860 results back. On Tue, Jun 24, 2014 at 10:20 AM, shai katzir wrote: > It's getting a little weird. > I run the next query : >

Re: [Neo4j] How I can create index (schema, legacy) after importing data(by batch inserter) from neo4j shell

2014-06-30 Thread Michael Hunger
Yes, you can still use legacy indexes for fulltext, numeric indexes and relationship indexes, but please note that writing to those is still a manual process (at least for numeric indexes). Otherwise you can configure node_auto_index or relationship_auto_index to be semi-automatic. See: http://jex

You're welcome. I created index in neo4j shell. It works. But the command schema --await must be schema await -l Item -p itemId. Another question is: as I understand, until now neo4j doesn't support schema index for relationship index, numeric range... Could i make legacy index in neo4j shell

Thank you Michael. I have read/watched most of the resources you linked to (all very useful), so I presume I have a good enough understanding of the language. I guess I wanted confirmation of my understanding and assumptions in practice. Regarding the large vs. small write queries, I don’t have

Hi, there is a number of resources for optimizing Cypher queries. We had the webinar: http://watch.neo4j.org/video/84900121 and blog posts from Wes: http://wes.skeweredrook.com/cypher/ and Mark http://www.markhneedham.com/blog/category/databases-2/neo4j/ and Luanne http://thought-bytes.blogspot.d

Re: [Neo4j] HA load balancer in Windows Cluster.

2014-06-30 Thread Michael Hunger
Afaik you have to setup a load balancer of some kind (or you use smart clients). That can be something like dns-round-robin if you're only reading, but if you also write to the cluster, you'll have to look into consistent routing (writing to master). See here: http://docs.neo4j.org/chunked/milest

[Neo4j] HA load balancer in Windows Cluster.

2014-06-30 Thread Paul Damian
Hi, I have a HA cluster containing 2 Neo4j instances running on VMs that are included in a Windows Failover Cluster. Both VMs run Windows Server 2012 R2. My question is: do I still have to set up a load balancer for the HA Cluster or is the load balancer running on cluster sufficient? Thanks,

[Neo4j] One medium/large Cypher query vs. several smaller queries performance

2014-06-30 Thread b
For mostly write-based queries, does the query engine perform better with one medium/large Cypher query or several smaller queries in succession? I am using the HTTP transactional endpoint and sending all statements in one request, so latency is constant. Also, is there a general resource/listi

You could probably call prettify on them, which uses a simpler but similar parser. Otherwise right now there is no way since the parse methods were removed. Perhaps it makes sense to raise a github issue for a "validate()" or compile() method on execution-engine. Which would validate the query an
