In a Python Google App Engine app I'm writing, I have an entity stored in the datastore that I need to retrieve, make an exact copy of it (with the exception of the key), and then put this entity back in.

My thinking was to do this: #theThing = a

I'm working on a project with already deployed indexing to google cloud datastore. We are missing index.yaml, is it possible to recreate index.yaml automatically?

Say I have a picture gallery and a picture could potentially have 100k+ fans. Which ndb design is more efficient? class picture(ndb.model): fanIds = ndb.StringProperty(repeated=True) ... [other picture properties] or class picture(ndb.model): ... [other picture properties] class fan(ndb.model): pictureId = StringProperty() fanId = StringProperty() Is there any limit on the number of items you can add to an ndb repeated property and is there any performance hit with storing a large amount of items in a repeated property? If it is less efficient to use repeated properties, what is their intended
