文件数量: 3000

单个文件大小: 10 MB

150 MB max combined size of code files
10 MB max individual size of any file
1000 files max per directory (not counting files in subdirectories)

为了减少文件数目可用以下办法zip压缩一下,修改app.yaml

- url: /ckeditor/.*
  script: $PYTHON_LIB/google/appengine/ext/zipserve

- url: /microemulator/.*
  script: $PYTHON_LIB/google/appengine/ext/zipserve

有人说只支持一个zip压缩包,我试了下,不只支持一个,多个没问题.
