We are using Oak embedded in a web application, and are now experiencing
significant delays in async indexing. New nodes added are sometimes not
available by query for up to an hour. I’m hoping you can identify areas I
might explore to improve this performance.
We have multiple instances of the web application running with the same Mongodb
cluster connected via SSL. Our Repository constructor is:
ns = new DocumentMK.Builder().setMongoDB(createMongoDB()).getNodeStore();
Oak oak = new Oak(ns);
LuceneIndexProvider provider = new LuceneIndexProvider();
Jcr jcr = new Jcr(oak).with((QueryIndexProvider) provider).with((Observer)
provider)
.with(new LuceneIndexEditorProvider()).withAsyncIndexing();
repository = jcr.createRepository();
The web application creates the repository at start up, and disposes of it as
shutdown. We have no observers registered at all, but do have 6 lucene indexes
defined. The index that is currently giving me heartburn looks like below.
Where would I start to find what is dragging performance down so drastically?
