When I compile my GAE/GWT (Java) project (compiling all 6 permutations), the whole WAR folder has a weight of 93.9 Mo on my computer (extended Mac OS journaled). When deployed on GAE, the Admin console (Quota Details page) shows that my app takes 18% of the free quota. Meaning 180Mb. How is this possible ? I am missing something ? Is google using a filesystem with big blocks ?? How to optimize the usage of the available storage space ? I’m already JARing my ‘classes’ folder, but the gain (in terms of space…) is not relevant.
The biggest problem (from my point of view) is that my own GWT + server side code + ‘external’ library (PDFJet) is taking a tiny 1.9Mb. All the rest (>91Mb) is taken by appengine’s and datanucleus own libraries. Why do we need to include those in the deployment ? They are used by everyone. I think it would be better for all of us when these would be centrally and automatically deployed. I don’t get it.
Any advices or comments on this ?
You need to ensure GWT post compilation output is tuned towards production deployment and in your case for “cloud” .
Ensure for Production deployment
1) GWT Compiler flag for STYLE IS OBF
2) GWT Compilation turns off stack trace emulator feature. In .gwt.xml
Ensure for Cloud deployment
1) GWT Compiler flag for extra and deploy is used to direct away mostly deployment redundant files away from WAR file. I am guessing you have massive folder called deploy in your WEB-INF.
