I've got simple JDO entity with two String attributes 1) If I load the entity from database, change one attribute and write it back - how many writes to indexes I should expect? (2 for the entity (key + key index) + 2 for changed attribute OR 2 for the entity + 4 for all attributes including those I didn't touch)?
2) if I use the entity for long time and then decide to change the structure and I let say remove one attribute and keep only one, then I delete/re-update all my entities in db. Can I expect that indexed data for the removed entity will be deleted and do they stay in datastore and have to be cleaned by admin/manually? I could see some strange issues with my app for which I was changing the db structure pretty regularly - I ended up with almost empty database (went down from 100k entities to 2k entities) but the datastore still shown 95% full (so my guess would be lost indexes?). I had to move the app to different appname as actually my ticket in bug track for gae is still after 30 days open and not resolved.
