The target directory will contain neo4j-batchinserterindexprovider-contrib-<version>.jar file, which can be imported to your project.

The BatchInserterIndexProvider API is documented here: http://components.neo4j.org/neo4j/1.7/apidocs/org/neo4j/unsafe/batchinsert/BatchInserterIndexProvider.html
This library contains the following contributed BatchInserterIndexProvider classes using MongoDB, Redis or Memcached as the data store.
Example:
BatchInserter inserter = BatchInserters.inserter( "target/neo4jdb-batchinsert" );
BatchInserterIndexProvider indexProvider = new MongoBatchInserterIndexProvider( inserter );
Map<String, String> config = MapUtil.stringMap( "mongo.db.host", "localhost", "mongo.db.port", "27017", "mongo.db.name", "graph_db", "mongo.collection.name", "neo4j_batch_index" );
BatchInserterIndex actors = indexProvider.nodeIndex( "actors", );
actors.setCacheCapacity( "name", 100000 );
Map<String, Object> properties = MapUtil.map( "name", "Keanu Reeves" );
long node = inserter.createNode( properties );
actors.add( node, properties );
actors.flush();
indexProvider.shutdown();
inserter.shutdown();
The MongoBatchInserterIndexProvider implements caching the same way the LuceneBatchInserterIndexProvider does.
The query() methods in the BatchInserterIndex interface are not implemented.
Indexes are always written to MongoDB at the time they're added (or removed), and flush() effectively does nothing. Using flush() is still encouraged, should the implementation change in the future.
Example:
BatchInserter inserter = BatchInserters.inserter( "target/neo4jdb-batchinsert" );
BatchInserterIndexProvider indexProvider = new RedisBatchInserterIndexProvider( inserter );
Map<String, String> config = MapUtil.stringMap( "redis.db.host", "localhost", "redis.db.port", "6379" );
BatchInserterIndex actors = indexProvider.nodeIndex( "actors", );
Map<String, Object> properties = MapUtil.map( "name", "Keanu Reeves" );
long node = inserter.createNode( properties );
actors.add( node, properties );
actors.flush();
indexProvider.shutdown();
inserter.shutdown();
The RedisBatchInserterIndexProvider does not do caching internally. It's largely redundant given the way Redis works.
