Is it not possible at this time to change the scaling configuration of your appengine-web.xml
or app.yaml
without redeploying the module/service.
The most control over scaling one can have at runtime is with the ModulesService. With this, one can determine the number of instances currently running of a given module-version and can start/stop a given module-version using the startVersion
and stopVersion
methods. Though quite limited, you are granted some control.
If appengine-web.xml
/app.yaml
configuration at runtime is a feature you would like to see implemented, feel free to file a feature request on the App Engine public issue tracker provided a thorough business case.
