Today we are happy to announce the 1.3.5 release of the App Engine SDK for both Python and Java developers.Due to popular demand, we have increased the throughput of the Task Queue API, from 50 reqs/sec per app to 50 reqs/sec per queue. You can also now specify the amount of storage available to the taskqueue in your app, for those with very large queues with many millions of tasks. Stay tuned for even more Task Queue scalability improvements in the future.Additionally, in this release we’ve also added support for precompilation of Python source...

How App Engine served the Humble Indie Bundle
Posted on 08:08 by Unknown
This is a guest post from Jeffrey Rosen, of Wolfire Games.Recently, Wolfire Games, joined by four other independent video game developers and two charities, put on a pretty unusual promotion: The Humble Indie Bundle. For twelve days, you could have gone to the promotional site and paid what you want (divided any way you choose among the developers, the EFF, and the Child's Play Charity) for a bundle of independent video games, all compatible with Mac, Windows, and Linux.The reason why I've been invited to write this guest blog post is because...

Datastore Outage and Unapplied Writes Issue
Posted on 09:48 by Unknown
We have completed the post-mortem on the Datastore outage App Engine experienced two weeks ago on May 25th. We greatly appreciate your patience in this.A very small percentage of apps (approximately 2%) have been affected by unapplied writes as a result of the outage. “Unapplied writes” are writes that did not get replicated to the secondary Datastore before completing the fail over process. We want to stress that these unapplied writes do not impact the transactional consistency and have not corrupted application data. Instead you can think of...

Datastore Performance Growing Pains
Posted on 15:40 by Unknown
As many of you know, App Engine’s Datastore performance has been seriously degraded over the last few weeks. In addition to May 25th’s 45 minute Datastore outage, applications have seen an increased latency and thus errors as a result of timeouts. As a rough estimate, we have seen Datastore latency increases of around 2.5x. Comparing April 1st to June 1st on the Status Site shows this trend. These issues in turn have caused problems with other parts of the App Engine service that also rely on the Datastore, such as Task Queues and the Admin Console.There...

Open sourcing Thoughtsite - A discussion forum designed for Google App Engine
Posted on 16:33 by Unknown

Editor's Note: Cross-posted from the Open Source at Google Blog.Google App Engine is a powerful system, designed to take all the pain of infrastructure management and performance scaling out of web application programming. App Engine applications are easy to build, easy to maintain, and easy to scale as your traffic and data storage needs grow.While there are a lot of open source projects available to learn how to use App Engine, there have been...
