Application under Google Apps Domain

So easy to use:

Essentially used for access rights

Users - practical

UserService userService = UserServiceFactory.getUserService();User user = userService.getCurrentUser();String email = user.getEmail();

Used to send new release notifications to users

Incoming e-mails to give Go/No Go instructions

Mail - both ways

Allows quick interaction with the app like:

give Go/No Go instructions.get quick stats

XMPP - 'cause it's fun !

Statistics queries are quite heavy.

Memcache is used to avoid doing the same thing twice.

Significantly improves response time.

Involves few lines of code:

Put in a singleton, can be used quickly from anywhere:

Memcache - a must use !

CacheFactory cacheFactory = CacheManager.getInstance().getCacheFactory();Cache cache = cacheFactory.createCache(Collections.emptyMap());

MC.get().put(key, value);[...]String value = MC.get().get(key);

Response time improvementsExporting data to Spreadsheet (combined with Cursors)

Task Queues - GAE threads

Valeo Market

Currently:APKs (~80KB) are persisted as blobs.Each user gets a link to a download servlet.APKs are served out from Datastore

In the works:�APKs will be uploaded to the Blobstore.Each user will get a download link by e-mail.APKs will directly be served from the Blobstore.

Blobstore - to come

APIs

Google Spreadsheets APIData export to Spreadsheets (and then to CSV)
