John,
Thanks a bunch. Here is the reason why I need to add a prefix to the key.
The scenario -
I will be implementing pagination (of the data returned) as described in
and for the sort order I wanted to use the Key. However, if the key also
has the date of creation embedded in it then the sort
You could use DatastoreService.allocateIds()
But why would you want to do this? If its to make the ids look nice
then you could just add and remove the string yourself before looking
up the key. Probably better to have a date property rather than
include it in the key.

First off thanks for your time.
I would like to generate a key that is a concatenation of a string with an
datastore generated key. Is there anyway to do that?
I want my keys to be "appname" + datastore generated key or say generate a
key that is currentdate + datastore generated key
Any sugges
