Re: [appengine-java] Does JDO auto remove indexes that now have unindexed properties?
Wild guess: If you load an entity in JDO and set a property to be exactly what it was before, this won't actually flag the entity as dirty. It won't be written when you commit the session. I don't know how you would force a write using JDO.

Re: [appengine-java] Does JDO auto remove indexes that now have unindexed properties?
Mark, Interesting that it does this. One thing you might try: 1. Run a mapper job 2. Read all the entities using the low level API 3. Explicitly set properties using the low level API's setProperty() and setUnindexedProperty() methods 4. Save entities back to the datastore This definitely should remove the indexes. -- Ikai Lan Developer Programs Engineer, Google App Engine plus.ikailan.com | twitter.com/ikai On Thu, Oct 13, 2011 at 6:23 AM, markabrucey markabru...@gmail.com wrote: Basically I have gone through my datastore persist-able classes and have annotated properties that I never need to query on like this: @Extension(vendorName=datanucleus, key=gae.unindexed, value=true) private Long random; I needed to test whether or not JDO removed the index when I changed the POJO by annotating a property as unindexed.
