Here's how we initialize non-lucene indexes in a spring environment;
public class RepositoryConfiguration implements DisposableBean {
[...]
public Repository getRepository() throws ContentException {
NodeStore nodeStore = null;
segmentStore = new FileStore(new File(oakRepositoryPath), 256);
nodeStore = new SegmentNodeStore(segmentStore);
oakRepository = new Jcr(nodeStore)
.with(new LocalInitialContent())
.withAsyncIndexing()
.createRepository();
return oakRepository;
}
public class LocalInitialContent implements RepositoryInitializer,
NodeTypeConstants {
@SuppressWarnings("unused")
private static NodeState createInitialContent() {
NodeBuilder builder = EMPTY_NODE.builder();
new InitialContent().initialize(builder);
return ModifiedNodeState.squeeze(builder.getNodeState());
}
@Override
public void initialize(NodeBuilder builder) {
// optionally set up lucene full-text index
createDefinition("jcr:name", index);
createDefinition("ka:assetType", index);
[.. lots of other property indexes ..]
}
private void createDefinition(String definition, NodeBuilder index) {
IndexUtils.createIndexDefinition(index, definition, true, false,
ImmutableSet.of(definition), null)
.setProperty("reindex", true);
}
}
In addition you would want a counter index, set up something like
NodeBuilder entry = index.child("counter")
.setProperty(JCR_PRIMARYTYPE, INDEX_DEFINITIONS_NODE_TYPE, NAME)
.setProperty(TYPE_PROPERTY_NAME, "counter");
But I haven't been able to get oak to make use of it if configured
this way yet.
