Janne,
You're correct on how the delta import works. You specify 3 queries:
- deletedPkQuery = query should return all "id"s (only) of items that were
deleted since the last run.
- deltaQuery = query should return all "id"s (only) of items that were
added/updated since the last run.
- deltaImp
How did it work before SOLR-811 update? I don't understand. Did it
fetch delta data with two queries (1. gets ids, 2. gets data per each
id) or did it fetch all delta data with a single query?
