> OAK-2247 introduced the copy-on-write feature for lucene index in Oak. This feature may result in a NodeBuilder updated by multiple threads concurrently. New index files are first stored on the local filesystem and then copied asynchronously into the repository. At the same time the async index update thread manipulates the node builders as well.
> With MongoMK this results in unexpected conflicts and failed async index updates.
