Hi radaczynski,

Java and Python apps run in the same environment (eg, you can have one
major version be Python, and another Java), so yes, the same applies
to Python. We don't currently have plans to change this, as alternate
major versions using the same datastore is essential for most people
deploying and rolling out new versions.

 Hi all,

 I have found info in the Javadocs that although there can be multple
 versions of the app, there is only one datastore for all of them. Is
 it the same for python? Are there any plans to version the datastore
 as well? Or should the apps just roll their own versioning scheme and
 data migration?

hey nick

is there any optimized way to have a python app call a java app in the
same GAE application? my guess is no, except through UrlFetch but I
figured I would ask anyway

also, do Python/Java versions in same GAE app share teh same memcache
as well?

Currently URLFetch is your only option. Once there's Java support for
Task Queues, though, you could do messaging in one direction by having
the non-default version enqueue a task queue item for the default
version.

 as well?

Yes.

2009-07-31 Thread Jaap Taal
I'd also like to know whether different versions of apps share the same
memcache
**
Does app engine prefix memcache keys? Or does app engine provide an other
means of key-separation?
Basicly what I would like to know: Do you have to include a versionnumber in
your own memcached keys or does app engine take care of this...
