tAzureStorageDelete – Docs for ESB ESB 7.x

tAzureStorageDelete

Deletes blobs from a given container for an Azure storage account according to the
specified blob filters.

tAzureStorageDelete Standard properties

These properties are used to configure tAzureStorageDelete
running in the Standard Job framework.

The Standard
tAzureStorageDelete component belongs to the Cloud family.

The component in this framework is available in all Talend
products
.

Basic settings

Property Type

Select the way the connection details
will be set.

  • Built-In: The connection details will be set
    locally for this component. You need to specify the values for all
    related connection properties manually.

  • Repository: The connection details stored
    centrally in Repository > Metadata will be reused by this component. You need to click
    the […] button next to it and in the pop-up
    Repository Content dialog box, select the
    connection details to be reused, and all related connection
    properties will be automatically filled in.

This property is not available when other connection component is selected
from the Connection Component drop-down list.

Connection Component

Select the component whose connection details will be
used to set up the connection to Azure storage from the drop-down list.

Account Name

Enter the name of the storage account you need to access. A storage account
name can be found in the Storage accounts dashboard of the Microsoft Azure Storage
system to be used. Ensure that the administrator of the system has granted you the
appropriate access permissions to this storage account.

Account Key

Enter the key associated with the storage account you need to access. Two
keys are available for each account and by default, either of them can be used for
this access.

Protocol

Select the protocol for this connection to be created.

Use Azure Shared Access Signature

Select this check box to use a shared access signature (SAS) to access the
storage resources without need for the account key. For more information,
see Using Shared Access Signatures
(SAS)
.

In the Azure Shared Access Signature field displayed,
enter your account SAS URL between double quotation marks. You can get the
SAS URL for each allowed service on Microsoft Azure portal after generating
SAS. The SAS URL format is
https://<$storagename>.<$service>.core.windows.net/<$sastoken>,
where <$storagename> is the storage account name,
<$service> is the allowed service name
(blob, file,
queue or table), and
<$sastoken> is the SAS token value. For more
information, see Constructing the Account SAS
URI
.

Note that the SAS has valid period, you can set the start time at which the
SAS becomes valid and the expiry time after which the SAS is no longer valid
when generating it, and you need to make sure your SAS is still valid when
running your Job.

Container name

Enter the name of the container from which you need to
delete blobs.

Blob filter

Complete this table to select the blobs to be deleted.
The parameters to be provided are:

  • Blob prefix: enter
    the common prefix of the names of the blobs you need to
    delete. This prefix allows you to filter the blobs which
    have the specified prefix in their names in the given
    container.

    A blob name contains the virtual hierarchy of the blob itself. This
    hierarchy is a virtual path to that blob and is relative to the container where that
    blob is stored. For example, in a container named photos, the
    name of a photo blob might be 2014/US/Oakland/Talend.jpg.

    For this reason, when you define a prefix, you are actually designating a
    directory level as the blob filter, for example, 2014/ or 2014/US/.

  • Include
    subdirectories
    : select this check box to
    select all of the sub-folders and the blobs in those folders
    beneath the designated directory level. If you leave this
    check box clear, tAzureStorageDelete deletes only the blobs
    directly beneath that directory level.

Die on error

Select the check box to stop the execution of the Job when an error
occurs.

Clear the check box to skip any rows on error and complete the process for
error-free rows. When errors are skipped, you can collect the rows on error using a Row > Reject link.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at the Job level
as well as at each component level.

Global Variables

CONTAINER

The name of the blob container. This is an After variable and it
returns a string.

ERROR_MESSAGE

The error message generated by the component when an error occurs. This
is an After variable and it returns a string.

Usage

Usage rule

This component can be used as a standalone component of a Job or
subJob.

Prerequisites

Knowledge about Microsoft Azure Storage is required.
