I could update jira with the new version, but would have to create a clean patch that applies again the lucene head. My local copy is diverged due to a number of uncommitted patches and so patches generated from it contain other stuff. My use case for parallel subindexes is as an enabler for fast bulk updates. Only the subindexes containing changing fields need to be updated, so long as the update algorithm does not change doc-ids. Even though this requires rewriting entire segments using techniques similar to those used in merging (but not purging deleted docs), I'm still getting 30x (when many fields changed) to many hundreds-x (when only a few fields changing) faster update performance than the batched delete-add method on very large indexes (million of documents, some very large).
