I found out more about this behavior.
This is not due to admin page restriction but to malformed URLs i

The url is in form

Hi Chris,
You need to specify the parent at creation time. There's no way to modify
the parent of an entity after it's created.
Bear in mind that updates to an entity group are limited to roughly 1QPS -
so putting all your entities in one entity group is rarely a good idea.

Hi Jason,
The current implementation of the datastore mapper uses lexicographical

Are you sure this isn't a caching issue? It's likely that the user's browser

Yes you can scale further. I think it is mentioned in the talk as well.
Make MessageIndex a child of Message.
Add multiple MessageIndex entities per Message.
What I would do is create a new MessageIndex per Message on each subscriber.
Then a cron job would periodically compact the MessageIndexes
So essentially you are suggesting to create new MessageIndex per Message per
subscriber. In case we happen to have 1 subscribers, for every message
that is posted we would create 1 MessageIndex entities. Is that what you
