Hi Nick, thanks for your reply! yes indeed a numeric id would be more

The reason I'm asking is, I want to do a random query. I want to
select a random entity from an entity group. I thought if the key is
distributed like this, then I could generate a random string like it
myself, and simply query for the first result bigger than this. Is
this viable?

Nick,
can we consider what you write below to be part of the API or an

Thanks
In the case of 'stringified' keys, what you are seeing is the base64
encoding of the protocol buffer containing the key. You can verify this by
