Hi,
Yes, the class Entity by Google only supports the core types defined
in the Dev Guide.
1 question : it seems that you are trying to mix high-level (JDO) and

that ?

Hi,
Yes: why don't you only work with JDO and use its persistence manager
to store your entities? The pm of jdo will handle translation between
annotated pojos and datastore transparently for you and then
drastically reduce your code size.
N.B; I personnally switched from JDO to Objectify: much

Hi MG,
Sharded counters help solve the concurrent write contention for an
entity.
Time (to the accuracy of milliseconds) helps to provide a one way
arrow towards a unique value.
Each request itself could be associated with an identity (this is up
to you, perhaps time in the request header).
Hi Didier,
Thank you for pointing out the easier approach of using JDO
PersistenceManager APIs to do unit testing. I missed the point that the same
benefits provided by these high-level APIs are equally applicable for unit
testing as well. I wrote that code basing purely on the official

You need to do it like this:

However, unless you've normalized your dates on midnight or something I

What are you building? With distributed systems, it can be tricky to do some
things. A single, scalable, atomic counter is an implementation for a
solution, not a solution to a problem. There may be an alternate
implementation that'll make your life easier but solve the problem at hand.

Ikai, you are right - I don't need a counter, a sequence of unique and
growing numbers will do. And I think I can make a scalable numeric
sequence by combining a sharded counter with a memcache counter (and
an occasional transaction). I'll post my solution when it's done.

Sweet. Remember that Memcache's INCR operation IS atomic.
