So I'm coding away my baby steps in Python, feeling all proud because I've got about 80% (ha!) of the site that I'm using as a test project converted over, when I open a new tab to look once again at the syntax for the templating language and BAM! I see "Java Early Look" on the left hand of the page.
Seriously? Java? They actually did it? Trembly-hands time, but I managed to click to this post on the Google App Engine Blog before the excitement got to me and I had to make a cup of tea.
But there's even more, including long awaited support for cron jobs, a Secure Data Connector so that App Engine applications can access data from behind your firewall, and a new version of GWT that can work with the Java version of App Engine as a back end. Empires will surely rise and fall due to this release; I wonder when they'll be adding support for .net? (Answer: Never!)
Secure Data Connectors look particularly interesting. It all depends of how fast it works of course, but I can see how it might enable mash-ups between relational data held on your own private servers and big-table data held in the app engine data store. I had been wondering if Google were going to address the fact that Microsoft is including SQL Server support in Azure (though we have yet to see how well that scales in practice), and this provides at least a partial answer.
There's also intriguing talk in the blog post of something they call Database Import: "move GBs of data easily into your App Engine app. Matching export capabilities are coming soon, hopefully within a month." Unfortunately the link they give points to the old how-to page on uploading data from CSV files. Maybe they'll fix the link, or maybe that page will get updated soon.
