获取 Azure 数据湖中使用了多少磁盘

Question

I'm using Azure.Storage.Files.DataLake to programmatically interact with Azure.

It looks like I can get the size of a given file with

var props = await fileClient.GetPropertiesAsync();
var fileSizeInBytes = propriedades.Value.ContentLength;

(where fileClient is an instace of DataLakeFileClient )

DataLakeDirectoryClient class offers a similar API, but ContentLength is always zero.

I would like to know how to get the size of:

1. a directory (with DataLakeDirectoryClient )
2. a file system (with DataLakeFileSystemClient )

Answer 1

You can use, DataLakeStoreFileSystemManagementClient.FileSystem.GetContentSummary:

var client = new DataLakeStoreFileSystemManagementClient(credentials);
ContentSummaryResult result = client.FileSystem.GetContentSummary(dataLakeAccount, path);
var dirSize = result.ContentSummary.Length;

For further details you can refer Documentation .
