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

The Standard tAzureStorageQueueList 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.

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 QueueName that stores the name of each queue to be returned.

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.

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.

ERROR_MESSAGE

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

Usage
