问题描述
在python中，这是我如何从Azure blob访问CSV
in python this is how I would access a csv from Azure blobs
storage_account_name = "testname"
storage_account_access_key = "..."
file_location = "wasb://example@testname.blob.core.windows.net/testfile.csv"
spark.conf.set(
"fs.azure.account.key."+storage_account_name+".blob.core.windows.net",
storage_account_access_key)
df = spark.read.format('csv').load(file_location, header = True, inferSchema = True)
如何在R中做到这一点?我找不到任何文档...
How can I do this in R? I cannot find any documentation...
推荐答案
AzureStor 程序包为Azure存储提供了R接口，包括文件，blob和ADLSgen2.
The AzureStor package provides an R interface to Azure storage, including files, blobs and ADLSgen2.
endp <- storage_endpoint("https://acctname.blob.core.windows.net", key="access_key")
cont <- storage_container(endp, "mycontainer")
storage_download(cont, "myblob.csv", "local_filename.csv")
请注意，这将下载到本地存储中的文件.从那里，您可以使用标准的Sparklyr方法摄取Spark.
Note that this will download to a file in local storage. From there, you can ingest into Spark using standard Sparklyr methods.
