There should never be a need to implement your own GraphDatabaseService or IndexManager... instead these are the things to do to provide your own index implementation:
- Create your own SphinxIndexProvider, inspired by LuceneIndexProvider<https://svn.neo4j.org/components/lucene-index/trunk/src/main/java/org/neo4j/index/impl/lucene/LuceneIndexProvider.java>. It will extend IndexProvider<http://components.neo4j.org/neo4j-examples/1.2.M02/apidocs/org/neo4j/graphdb/index/IndexProvider.html>which gets loaded together with the kernel and can therefore participate in recovery. - Specify a unique service name f.ex. "sphinx". - When creating indexes<http://components.neo4j.org/neo4j-examples/1.2.M02/apidocs/org/neo4j/graphdb/index/IndexManager.html#forNodes%28java.lang.String,%20java.util.Map%29>(accessing for the first time) supply "provider": "sphinx" in that config map. Or put neo4j config (to your EmbeddedGraphDatabase) "index": "sphinx" so that the provider by default is "sphinx"... then you can just use the normal accessor, i.e. graphDb.index().forNodes( "my-index" ). - Make sure you have an META-INF/services/org.neo4j.kernel.KernelExtension containing your SphinxIndexProvider (common java service API thingie). The XaDataSource/XaConnection/XaResource implementation needed to implement an index is a bit tedious and is bound to be simplified in the future. Until then you can just look at how the LuceneIndexProvider does things and copy that. This information is, as you pointed out, missing from the wiki page... I'll add it! 2010/11/3 Balazs E.
