Right now we are using Neo4j 1.9.9 version(embedded mode) with tinkerpop blueprints 2.4 API. We are planning to upgrade our Neo4j to 2.3. But I see that blueprints is not compatible with neo 2.3. Since our system is stable now we are trying to upgrade our neo4j without disturbing the crud layer much.
1.Can any one help me here to understand why blueprints is not compatible with 2.3?
2. If I plan to use spring-data from my understanding it is not for embedded mode.Can some one share if you faced this scenario and how you approached the problem?

I have an application which loads some external data based on gremlin.
I want to use it to load the data into a Neo4j database.
I saw that there was partial support for gremlin in previous versions but couldn't find any solution for latest version.
I'll be happy to hear if it is still possible and how can it be done.
At this point, TinkerPop expects to support 3.4.11 in its future 3.5.0 release (here) which is yet several months away. For TinkerPop to support 4.0 it would need a fresh release of the neo4j-tinkerpop-api-impl to be released with that version. It seems an issue has been created for that here.
I have several applications created with grails 1.2.2. I need to modify one of these applications to work with multiple datasources. It seems that my best option is to upgrade to a new version of grails. I'm worried that trying to go straight to grails 3 will cause major issues, but am not sure which versions to step through if I'm going to upgrade gradually. Any advice? I apologize for this being so open ended.
The first info about support for multiple databases in official docs exists in version 2.0.0:
http://docs.grails.org/2.0.0/guide/conf.html#multipleDatasources
Check out this guide for upgrade:
http://docs.grails.org/2.0.0/guide/gettingStarted.html#upgradingFromPreviousVersionsOfGrails
I understand that was possible in previous versions, and I also understand that version 4.0.0 is a total redesign towards a server-first approach, but nowhere in the documentation it is said whether embedded mode is supported.
4.0.0.RELEASE is server only. Embedded support will be available in a future release.
Which version of the neo4j plugin should I be using with grails?
The official grails site claims that version 2.0.0-M02 is the latest, but the associated documentation is from version 1.x. Is there later documentation? Has much changed?
I'm interested in particular in how the node structure has been changed to represent the domain model. Is it now the case that labels are being used instead of SUBREFERENCE nodes now?
I'm looking for a way to user Neo4j 2.0 in a Play 2.2.1 application.
Everything I find is only working with either an older version of Neo4j or Play 2.2.1. Like this: https://github.com/sgougi/play21-frames-neo4j-plugin
the current version off the plugin 1.2.1 supports play 2.2.1 and neo4j 1.9.5 using spring data.
Currently i am lifting the neo4j version to 2.0 Beta as Johannes already mentioned.
If you have any questions how this plugin works you can ask me and Johannes.
tuxBurner is developing a play-neo4jplugin and shares his code on github at https://github.com/tuxBurner/play-neo4jplugin . This plugin is really cool and i am enjoying it a lot in a lot of projects.
Currently this version runs on play 2.1.2 and neo4j 1.9.5, but he will release the next days the lift to play 2.2 and neo4j 2.0.0-RC1.
Just wait for a few more days and enjoy :)
Cheers,
Johannes
