AzureBlob Get - Data360_Analyze - Latest

Downloads files from a server using the Azure Blob protocol.

The AzureBlob nodes enable you to access data from Azure containers so that you can integrate your data flows with Azure. See:

• AzureBlob List
• AzureBlob Delete
• AzureBlob Put

Downloading a single file from an Azure Blob container

1. Drag an AzureBlob Get node onto the canvas. Then, in the Container property, specify the name of an Azure Blob container where the file that you want to download is located.
2. In the Object property, specify the name of the Azure object that you want to download, including the file type e.g. example_file.txt.
3. Provide your Azure account name and account key details in the AccountName and AccountKey properties.
4. In the Directory property, specify where to store the file that is downloaded.

Downloading multiple files from an Azure Blob container

1. Drag an AzureBlob List node onto the canvas and connect the listed files output to an AzureBlob Get node.
2. In the Container property of the AzureBlob List node, type the name of the Azure Blob container where the files that you want to download are stored.
3. Provide your Azure account name and account key details in the AccountName and AccountKey properties. Then, run the AzureBlob List node to generate a list of files in the specified container.
4. On the AzureBlob Get node, select the (from Field) variant of the Container property and specify the name of the input field that references the container name e.g. Container.
5. Select the (from Field) variant of the Object property, then specify the name of the input field that references the files that you want to download e.g. Object.
6. Provide your Azure account name and account key details in the AccountName and AccountKey properties.
7. In the Directory property, specify where to store the downloaded files. Then, run the AzureBlob Get node to download the files from the specified Azure container.

Example

You want to download all files with the "Product _A" prefix from an Azure container:

1. Drag an AzureBlob List node onto the canvas. In the Container property, type the name of the Azure container for which you want to list files, e.g. my-example-container.
2. In the ObjectPrefix property, type Product_A.
3. Provide your Azure account name and account key details in the AccountName and AccountKey properties.
4. Run the AzureBlob List node.

   The output of the AzureBlob List node is as follows:

   Container unicode	Object unicode	BlobType unicode	Size long	Modified datetime	Created datetime	ETag unicode	ContentType unicode	ContentMD5 unicode	Metadata unicode
   my-example-container	Product_A_1.txt	BLOCK_BLOB	20	2020-10-26T10:00:00-0400	2020-10-25T17:01:45-0400	"0x8D8713F56839283"	text/plain	9e53e712984923778166af==	{}
   my-example-container	Product_A_2.txt	BLOCK_BLOB	20	2020-10-25T10:14:20-0400	2020-10-25T09:11:12-0400	"0x8D8713F780376EB"	text/plain	F95EWR129866731230655a==	{}

   Tip: Only the objects with the specified prefix are listed.

5. Connect the listed files output of the AzureBlob List node to an AzureBlob Get node. On the Get node, select the (fromField) variant of the Container property and type the name of the input field that references the Azure container, in this case Container.
6. Select the (from Field) variant of the Object property, then specify the name of the input field that references the files that you want to download, in this case Object.
7. In the Directory property, specify where to store the downloaded files, e.g. C:\Users\<username>\Documents\AzureBlob_download.
8. Run the AzureBlob Get node to download the files from the specified Azure Blob container.
