Listing files in Google Cloud bucket with thousands of files.










0















I'm running a Node.js script to get the number of files in a bucket on Google Cloud Storage.



In a bucket with about 30K files, I get a result in a few seconds. In a bucket with about 300K files, I get the following error:

  • Your problem is that you are running out of memory to store the returned results. You will need to use the APIs and page the output. This will limit the number of items returned for each response.

Most of the methods that return lists offer a streaming version of said method. In this case you'll want to use bucket.getFilesStream()



bucket.getFilesStream()
.on('error', console.error)
.on('data', function(file)
// file is a File object.
)
.on('end', function()
// All files retrieved.
);


Alternatively you can disable auto pagination and manual page through the results



const callback = function(err, files, nextQuery, apiResponse) 
if (nextQuery)
// More results exist.
bucket.getFiles(nextQuery, callback);

;

bucket.getFiles(
autoPaginate: false
, callback);

    As pointed out in the comments you should use the Objects: list API to list large buckets.



    Also, if I am reading the library documentation correctly you can set the autoPaginate option to false and manually iterate over the results, without having to talk to the JSON api directly.

                  As pointed out in the comments you should use the Objects: list API to list large buckets.



                  Also, if I am reading the library documentation correctly you can set the autoPaginate option to false and manually iterate over the results, without having to talk to the JSON api directly.
