Azure Blob Storage Extension

The Azure Blob Storage extension provides reading and writing of formatted files to Azure Blob Storage containers.

Note: This is a Binary Storage Extension that is only used in combination with File Format extensions.

Settings

Source and sink require settings used to locate and access the Azure Blob Storage account. This can be done in one of two ways:

  • Using a ConnectionString that includes an AccountEndpoint and AccountKey
  • Using RBAC (Role Based Access Control) by setting UseRbacAuth to true and specifying AccountEndpoint and optionally EnableInteractiveCredentials to prompt the user to log in to Azure if default credentials are not available.

Source

An optional ReadBufferSizeInKB parameter can be used to control stream buffering.

{
    "ConnectionString": "DefaultEndpointsProtocol=https;AccountName=...",
    "ContainerName": "",
    "BlobName": "",
}

Or with RBAC:

{
    "AccountEndpoint": "https://<storage-account>.blob.core.windows.net",
    "ContainerName": "",
    "BlobName": "",
    "UseRbacAuth": true,
    "EnableInteractiveCredentials": true
}

Sink

An optional MaxBlockSizeInKB parameter can also be specified to control the transfer.

{
    "ConnectionString": "DefaultEndpointsProtocol=https;AccountName=...",
    "ContainerName": "",
    "BlobName": "",
}
