Hi There,
I have a few Java microservices and when I redeploy them, one of them needs
like 40 seconds after starting up (it's a dropwizard application) to load
data and do some computation to actually be ready to serve requests. This
extra time makes so GCP thinks the service is ready and
instance (e.g., no GCS direct bandwidth), in practice we can put
a bound using that.

I concur with the worry. Is there any _technical_ reason why it is a good
idea to do away with a spending limit? Can we get an instance limit
instead?
This is suddenly making standard non-scalable systems on AWS look better
than appengine!

From ejb-3.0-persistence-specification, section 3.2 I can read that
A managed entity instance is an instance with a persistent identity
that is currently associated
with a persistence context.
From this I understand that em.persist() (paragraph 3.1.1) should give
me the persistent identity.
Sorry I can't get your point about Optimistic Locking.
If I do some insert inside a transaction that is at least with
isolation level read committed I don't have any kind of problem with
versioning.
Can you please give me an example of how can I have such a problem ??
Thx.

I did some more tests, printing the key IMMEDIATELY AFTER the
em.persist and these are the results:
- OpenJPA (1.0.1): key assigned
- EclipseLink (1.0.1): key assigned
this with the results of yesterday's tests:
- Hibernate (3.4.0.GA): key assigned
- DataNucleus (1.1.5): key null

Hi,
I am following the Using the Google Plugin for Eclipse tutorial. I
have built the very simple hello world application. When I try to
deploy using the built in eclipse deploy feature I get the following:
Creating staging directory
Scanning for jsp files.
Scanning files on local disk.
I wonder also if java on GAE will consume more cpu resources which
implies higher costs when exceeding the free quotas..
Nobody here who can give a technical estimation on that?
