[Neo4j] Unrecovable transaction error
Hi to all, we recently (for 2nd time) engaged a transaction error using neo4j embedded. We need to investigate well about this error origin, BUT I need to understand how to resolve the following error: java.lang.RuntimeException: No mapping found for branchId[0x162374] The steps: 1) two users work on the application 2) one user receive a transaction error (sorry, not traced .. maybe an error on begin transaction) 3) shutting down the server (as usual) 4) restarting the server 5) receiving the error: java.lang.RuntimeException: No mapping found for branchId[0x162374] at com.tinkerpop.blueprints.pgm.impls.neo4j.Neo4jGraph.init(Neo4jGraph.java:58) at com.tinkerpop.blueprints.pgm.impls.neo4j.Neo4jGraph.init(Neo4jGraph.java:31) ..

I dont want to understand (in this help request) why and where I create the transaction error (maybe a not well closed transaction or other) but I need to understand HOW TO RECOVER a DB that generate the error at point 5 THAT DOES NOT START ANYMORE. :-( Thank you for your support !

Re: [Neo4j] Neo4j 1.2 is released
That's great ! A Happy New Year to all the Neo4j team members ! Gian Luca Farina Perseu 21Style / www.21-style.com On Thu, Dec 30, 2010 at 10:30 PM, Tobias Ivarsson tobias.ivars...@neotechnology.com wrote: Happy new year — happy new Neo4j version! The Neo4j team is happy to announce version 1.2 of the Neo4j graph database. Building on the line of milestone releases of Neo4j, version 1.2 contains only a few minor bug fixes over 1.2.M06, and should be very stable. The official announcement has been posted here: http://www.dzone.com/links/neo4j_12_final_prtporter.html If you like this version, please vote for the article on DZone, and share the link with your friends and colleagues. We would like to thank everyone on this mailing list, and all of our customers, who provided the bug reports, feedback, suggestions and patches that made this release what it is. You've already given us a lot of great ideas for the road ahead, but keep them coming, let's make Neo4j even better together! Your next stop, for downloading this version of Neo4j, is: http://neo4j.org/download The main new features in Neo4j 1.2 compared to Neo4j 1.1 are: * The Neo4j Server The Neo4j standalone server builds upon the RESTful API that was pre-released for Neo4j 1.1. The server provides a complete stand alone Neo4j graph database experience, making it easy to access Neo4j from any programming language or platform. Some of you have already provided great client libraries for languages such as Python, Ruby, PHP, the .Net stack and more. Links and further information about client libraries can be found at: http://www.delicious.com/neo4j/drivers * Neo4j High Availability The High Availability feature of Neo4j provides an easy way to set up a cluster of graph databases. This allows for read scalability and tolerates faults in any of the participating machines. Writes are allowed to any machine, but are synchronized with a slight delay across all of them. High Availability in Neo4j is still in quite an early stage of its evolution and thus still have a few limitations. While it provides scalability for read load, write operations are slightly slower. Adding new machines to a cluster still requires some manual work, and very large transactions cannot be transmitted across machines. These limitations will be addressed in the next version of Neo4j. Some other noteworthy changes include: * Additional services for the Neo4j kernel can now be loaded during startup, or injected into a running instance. Examples of such additional services are the Neo4j shell server and the Neo4j management interface. * Memory footprint and read performance has been improved. * A new cache implementation has been added for high load, low latency workloads. * A new index API has been added that is more tightly integrated with the database. This new index API supports indexing relationships as well as nodes, and also supports indexing and querying multiple properties for each node or relationship. The old index API has been deprecated but remains available and will continue to receive bug fixes for a while. * The Neo4j shell supports performing path algorithm queries. * Built in automatic feedback to improve future versions of Neo4j. See: http://blog.neo4j.org/2010/10/announcing-neo4j-12m01-and-focus-on.html Last but not least all known issues have been fixed. If you want more details, please read the change log and/or the announcements for the previous milestone releases.

Thanks Craig for all your informations I'll analize in deep in next days :-) Thank you very much!

I understand that for my purpouse Neo4j libraries are uncessary for me. Since you want an index, you want Neo4j Spatial :-) Craig (and excuse me to Anne for the intrusion), could you tell me how to managa at best some simple geo coordinates (lat e long) as Neo4j nodes ? I would suggest two double properties, latitude and longitude. Then pass these into the Neo4j Spatial index. If you do not want to write any code yourself for telling the index how to understand your node, the SimplePropertyEncoder can do this work for you, so you do not need to create a mapping between the node and the index. However, to use SimplePropertyEncoder, you do need to create a Geometry, like a Point, and pass that in. If you do not want to do that, take a look at SimplePropertyEncoder, it would be trivial to make a new version of that class that takes in two float or two doubles. I only need to store 2 properties (lat e long) some some nodes, then to retrieve the nearest points inside a box area with a center defined by a lat/long node Which is the best algorithm to do this ? Can I put lat e long as double property in a node, than find it by a lucene search ( lat between x and y lat, long between x and y long) ? I've not tried lucene for this, but if you store the position as lat and long on two properties in a node, and write a version of the encoder (as described above), then the RTree index would work on this data, and would be fast.

Re: [Neo4j] neo4j and GeoServer
Thank Peter for your reply. I'll try in next days if this code will help me ;-) Just to understand what I mean, I'm thinking about something similar: http://www.mongodb.org/display/DOCS/Geospatial+Indexing in particular the examples in paragraphs: Querying, Compound Indexes and Bounds Queries Have a good job !

We are thinking about a simple API which is doing what you describe, via the Neo4j Index API, see https://github.com/neo4j/neo4j-spatial/blob/300f4d1d1fbb92d6252d5be6dc334250c9514bc7/src/test/java/org/neo4j/gis/spatial/IndexProviderTest.java#L51 for an example. That would take care of all spatial internals once the index config is set up. Craig is working on such an interface. Until then, look at https://github.com/neo4j/neo4j-spatial/blob/300f4d1d1fbb92d6252d5be6dc334250c9514bc7/src/test/java/org/neo4j/gis/spatial/TestSearch.java for an example of searching with Neo4j Spatial.

However, it assumes you used Neo4j Spatial features to create the layers in the database in the first place. This must be done with Java code (or in the case of the wiki page example, use the included test cases to create test layers). I suggest run through the case described in the wiki page, and then review the test code used to create the layers in neo4j and see if that answers your questions. But I can also say that the answer to the question on 'how do we define the nodes properties' is that it is 'up to you'. We provide an extensible mechanism so that you can use whatever graph structure you want to create spatial data and provide an adapter to expose that as geometries to the GIS. To make life easier we have a few built in adapters you can pick if you do not want to build your own. There is a WKB adapter that stores the geometries as WKB in a single property of a node, there is a lat/long one that only supports points on one node, and there is a simple sub-graph one that allows polygons in sub-graphs, and finally the most complex one we have is the OSM model that supports the entire open streetmap graph in a very similar structure to OSM itself, but exposed as multiple layers to the GIS.
