tAzureStorageQueueOutput – Docs for ESB ESB 7.x

tAzureStorageQueueOutput

Adds messages to the back of an Azure queue.

Note that this component can only be used with Java 8.

tAzureStorageQueueOutput Standard properties

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

The Standard
tAzureStorageQueueOutput 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.

Queue name

Specify the name of the Azure queue to which the messages will be added.

Schema and Edit schema

A schema is a row description. It defines the number of fields
(columns) to be processed and passed on to the next component. When you create a Spark
Job, avoid the reserved word line when naming the
fields.

  • Built-In: You create and store the schema locally for this component
    only.

  • Repository: You have already created the schema and stored it in the
    Repository. You can reuse it in various projects and Job designs.

The schema of this component is predefined with one single column
MessageContent that stores the body of each message.

Click Edit
schema
to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • View schema: choose this
    option to view the schema only.

  • Change to built-in property:
    choose this option to change the schema to Built-in for local changes.

  • Update repository connection:
    choose this option to change the schema stored in the repository and decide whether
    to propagate the changes to all the Jobs upon completion. If you just want to
    propagate the changes to the current Job, you can select No upon completion and choose this schema metadata
    again in the Repository Content
    window.

Die on error

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