Easy Performance Profiling with Appstats

Since App Engine debuted 2 years ago, we’ve written extensively about best practices for writing scalable apps on App Engine. We make writing scalable apps as easy as possible, but even so, getting everything right can be a challenge - and when you don’t, it can be tough to figure out what’s going wrong, or what’s slowing your app down.Thanks to a new library, however, you no longer need to guess. Appstats is a library for App Engine that enables...

Read Consistency & Deadlines: More control of your Datastore

Last week we announced the 1.3.2 release of the App Engine SDK. We’re particularly excited about two new datastore features: eventually consistent reads, and datastore deadlines.Read Consistency SettingsYou now have the option to specify eventually consistent reads on your datastore queries and fetches.

App Engine joins the Google over IPv6 Program

The Google over IPv6 program allows ISPs with good connectivity to request IPv6 access for most Google services. In about a week, we'll be adding Google App Engine and the appspot.com domain to this program. This means that all App Engine apps will become accessible over IPv6 to anyone participating in the program!For most people, this won't require any changes to your code at all. If your App Engine code reads os.environ["REMOTE_ADDR"] in Python, or HttpServletRequest.getRemoteAddr() in Java, be aware that this value may be an IPv4 address, like...
