Hi all. We have an application which has been around for so long that it's still using doc IDs to key to an external database.
Obviously this won't work forever (even in Lucene 3.x we had to use a custom merge policy to keep it working) so we want to introduce application IDs eventually. We have two potential paths here: 1. Use our existing GUID field as the new unique ID and migrate to that (with the huge drawback that indexing GUID columns on the database is much, much slower than the current int column.) 2. Introduce a new application ID (either int or long) and somehow insert that into every document. The time it would take to pull every document out, add a field for the ID and index it again is too long to be desirable, so I'm wondering: is there some way we could add this field to every document without reindexing? Keeping Lucene 3.x as the limitation, that is... our 2.x-created indexes presumably won't open at all in 4.x without significant work.
