[google-appengine] Re: Multiple app versions - only one datastore?
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. -Nick Johnson On Thu, Jul 30, 2009 at 1:49 PM, radaczynskiradaczyn...@gmail.com wrote: 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.

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? thecheers brian On Jul 31, 8:47 am, Nick Johnson (Google) nick.john...@google.com wrote: 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.

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. also, do Python/Java versions in same GAE app share teh same memcache as well? Yes. -Nick Johnson thecheers brian On Jul 31, 8:47 am, Nick Johnson (Google) nick.john...@google.com wrote: 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.

[google-appengine] Re: Multiple app versions - only one datastore?
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... ** Jaap Taal [ Q42 BV | tel 070 44523 42 | direct 070 44523 65 | http://q42.nl | Waldorpstraat 17F, Den Haag | KvK 30164662 ] On Fri, Jul 31, 2009 at 2:52 PM, bFlood bflood...@gmail.com wrote: 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? thecheers brian On Jul 31, 8:47 am, Nick Johnson (Google) nick.john...@google.com wrote: 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.
