问题 Using NDB, it is possible to specify a projection for a query, allowing to limit the number of properties that are retrieved for the entities that match the query. However, I couldn't find anything in the documentation about how to specify a projection when using ndb.get_multi() , which always fetches complete entities. Is there a way to fetch only certain properties when using ndb.get_multi() ? 回答1: No, the projection feature only works for queries. There would be no advantage (in terms of

问题 I'm trying asynchronous processing support in servlet 3.1 with GAE J8 standard environment (no extensible environment). Basically I have a servlet annotated with @WebServlet(name = "MyServletName", urlPatterns = {"/dosomething"}, asyncSupported = true) and to obtain an instance of AsyncContext I call (in doPost method) final AsyncContext asyncContext = httpServletRequest.startAsync(httpServletRequest, httpServletResponse); But asynchronous processing support seems to have some problems in GAE

问题 My standard AppEngine application needs to perform changes in a Google Sheet documents (among others). To achieve this, I need to obtain a credential for service account, and somehow configure that it should act in behalf of a user. This method allows gives me default service account credentials: private static GoogleCredential getDefaultServiceAccountCredential() throws IOException { return GoogleCredential.getApplicationDefault() .createScoped(MY_SCOPES); } but it does not work in behalf of

问题 From within an App Engine app, is there a way to determine the project ID a GAE (App Engine) instance is running on? I want to access a big query table in the same project that the App Engine instance is running in. I'd rather not hard code it in or include it in another config file if possible. Edit: forgot to mention that this is from Python 回答1: You can get a lot of info from environment variables: import os print os.getenv('APPLICATION_ID') print os.getenv('CURRENT_VERSION_ID') print os

问题 I have an app in the Google App Engine Python 3 Standard Environment. I have it set up to group log entries by their request, as described in Writing Application Logs (in the "Viewing related request log entries" section). That page notes: The highest severity from the "child" log entries does not automatically apply to the top-level entry. If that behavior is desired, manually set the highest severity in the top-level entry. The top-level entry in question is the request log that App Engine

问题 TL;DR Is there a way to deploy App Engine modules in parallel? I've built a go application using Google's App Engine SDK for Go. This application defines multiple modules. These modules are self-contained, and do not require any sort of dependency across other modules. When I attempt to deploy the modules to the Google Cloud, I can't help but notice that the modules are uploaded sequentially. This would be fine if deployment was relatively quick, but each module requires it's own redundant
