[google-appengine] Re: Remote realtime FIFO implementation
Hey guys, thanks a lot for the answers. I really have to think about how I do it. Problems I see: - ds is too expensive, I await about 3 reads/write per second - RAM-cache will not work (as James X Nelson says, I mean it's not shared between instances, but I have to learn some more about RAM- concept of GAE) - as I understand channel api, it's only PUSH, so I can't push, because both clients are behind NAT, so I can pull only Sorry, I'm too tired today to understand all of James post ;) but I will be back tomorrow ;) Thanks again for the answers. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Remote realtime FIFO implementation
Hi all, I'm new to Google App Engine and I'm looking for an advice. I want write a remote FIFO for realtime access outside of GAE. This FIFO should contains small integers only and works as follows: - client A write integer-values to FIFO - client B reads the values 1-5 seconds later - after what the values are invalid and can be deleted - there are always only 2 client per FIFO - it should be possible to have x FIFOs in the app Importent for me: ability for realtime and concurrency, no deadlock etc. So, I'm new to GAE, wich service can I use for my App? Pull Queues are limited to 100 active queues, it's not enough for me. Should I use memcache? DB?

[google-appengine] using Guice in mapreduce mappers
I've created a couple of mapreduce mappers that successfully run. Now,
I wanted to use my existing classes (DAOs and Managers) from within
these mappers. I developed them for my existing GAE application (that
the mapreduce mappers are part of now). I use Guice in my GAE
application successfully. So how would I plug mapreduce mappers with
Guice DI - so far I have not succeeded with that?
So far I've got this going:
I do use Guice Servlet and I have defined
serve("/mapreduce/*").with(MyMapReduceServlet.class);
in MyServletModule along with my other servlets. mapreduce servlet is
defined:
@Singleton
public class MyMapReduceServlet extends MapReduceServlet {
All of them work including mapreduce servlet. But when I launch
mapreduce job I get NPE on injected property:
@Inject
private WineDAO wineDAO;
@Inject // not sure this is needed...
public DeleteAllMapper() {
super();
}
