azure-blob-storage

Loads from and saves to an Azure Blob Storage

Synopsis​

Loader:

azure-blob-storage <uri>

Saver:

azure-blob-storage <uri>

Description​

The azure-blob-storage loader connects to an Azure Blob Store to acquire raw bytes from a blob. The azure-blob-storage saver writes bytes to a blob in an Azure Blob Store.

By default, authentication is handled by the Azure SDK’s credential chain which may read from multiple environment variables, such as:

  • AZURE_TENANT_ID
  • AZURE_CLIENT_ID
  • AZURE_CLIENT_SECRET
  • AZURE_AUTHORITY_HOST
  • AZURE_CLIENT_CERTIFICATE_PATH
  • AZURE_FEDERATED_TOKEN_FILE

<uri> (Loader, Saver)​

A URI identifying the blob to load from or save to.

The saver will create directories and files if they do not exist and overwrite files if they already exist.

Supported URI formats:

  1. abfs[s]://[:<password>@]<account>.blob.core.windows.net[/<container>[/<path>]]
  2. abfs[s]://<container>[:<password>]@<account>.dfs.core.windows.net[/path]
  3. abfs[s]://[<account[:<password>]@]<host[.domain]>[<:port>][/<container>[/path]]
  4. abfs[s]://[<account[:<password>]@]<container>[/path]

(1) and (2) are compatible with the Azure Data Lake Storage Gen2 URIs 1, (3) is for Azure Blob Storage compatible service including Azurite, and (4) is a shorter version of (1) and (2).

Authenticate with the Azure CLI

Run az login on the command-line to authenticate the current user with Azure's command-line arguments.

Examples​

Read JSON from a blob obj.json in the blob container container, using the tenzirdev user:

load azure-blob-storage "abfss://tenzirdev@container/obj.json"
| read json
