问题 Is it possible to mass rename objects on Google Cloud Storage using gsutil (or some other tool)? I am trying to figure out a way to rename a bunch of images from *.JPG to *.jpg. 回答1: https://cloud.google.com/storage/docs/gsutil/addlhelp/WildcardNames gsutil supports URI wildcards EDIT gsutil 3.0 release note As part of the bucket sub-directory support we changed the * wildcard to match only up to directory boundaries, and introduced the new ** wildcard... Do you have directories under bucket?

Specify the path to php-cgi and gae_runtime_module.so when running the development server." I'm using a new Virtualbox machine with Ubuntu 15.10 and PhpStorm to test GAE.

问题 What should I know about FetchOptions withLimit, prefetchSize and chunkSize? The docs say the following: prefetchSize is the number of results retrieved on the first call to the datastore. chunkSize determines the internal chunking strategy of the Iterator returned by PreparedQuery.asIterator(FetchOptions) ... prefetchSize and chunkSize have no impact on the result of the PreparedQuery, but rather only the performance of the PreparedQuery.

问题 I am using Node.js on App Engine Standard and Flexible. In the logs viewer, is it possible to display application logs nested inside request logs? 回答1: Yes it is possible to correlate application logs and request logs.

When you do so, your logs are automatically annotated with the correct Trace ID (see docs for Bunyan)
