[hibernate-dev] "Live async" MassIndexer

I've written some ideas for MassIndexer improvements in the forum, to allow it to work in background using updates instead of wiping out the index, so that it doesn't prevent running applications to find results. (it's being asked now, but something I wanted to add anyway at some point) : https://forum.hibernate.org/viewtopic.php?f=9&t=1014063 An alternative would be to have it create a new index from scratch, and switch at the end, but this introduces the problem of applying changes of transactions which happen during the indexing; we could apply transactional changes to both, but this seems more complex than using the single index.
