tAzureSynapseBulkExec Standard properties

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

The Standard tAzureSynapseBulkExec component belongs to two families: Cloud and Databases.

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.

Use an existing connection

Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined.

When a Job contains the parent Job and the child Job, if you need to share an existing connection between the two levels, for example, to share the connection created by the parent Job with the child Job, you have to:

  1. In the parent level, register the database connection to be shared in the Basic settings view of the connection component which creates that very database connection.

  2. In the child level, use a dedicated connection component to read that registered database connection.

For an example about how to share a database connection across Job levels, see Talend Studio User Guide.

JDBC Provider

Select the provider of the JDBC driver to be used.

Host

Enter the IP address or the hostname of the database server or the Azure Synapse Analytics to be used.

If the SQL Server Browser service is running on the machine where the server resides, you can connect to a named instance through a TCP dynamic port by providing the host name and the instance name in this field in the format of {host_name}\{instance_name}. In this case, you can leave the Port field empty. See SQL Server Browser service for related information.

Port

Enter the listening port number of the database server or the Azure Synapse Analytics to be used.

If the SQL Server Browser service is running on the machine where the server resides, you can connect to a named instance through a TCP dynamic port by providing the host name and the instance name in the Host field and leave this field empty. See SQL Server Browser service for related information.

Schema

Enter the name of the Azure Synapse Analytics schema.

Database

Specify the name of the Azure Synapse Analytics to be used.

Username and Password

Enter the authentication data.

To enter the password, click the [...] button next to the Password field, enter the password in double quotes in the pop-up dialog box, and then click OK.

You can use Type 2 integrated authentication on Windows by adding integratedSecurity=true in the Additional JDBC Parameters field and leave these two fields empty. See section Connecting with integrated authentication On Windows at Building the connection URL for related information.

Additional JDBC Parameters

Specify additional connection properties for the database connection you are creating. The properties are separated by semicolon and each property is a key-value pair. For example, encrypt=true;trustServerCertificate=false; hostNameInCertificate=*.database.windows.net;loginTimeout=30; for Azure SQL database connection.

Table

Specify the name of the SQL Data Warehouse table into which data will be loaded.

Action on table

Select an operation to be performed on the table defined.

  • None: No operation is carried out.

  • Drop and create table: The table is removed and created again.

  • Create table: The table does not exist and gets created.

  • Create table if not exists: The table is created if it does not exist.

  • Drop table if exists and create: The table is removed if it already exists and created again.

  • Clear table: The table content is deleted. You have the possibility to rollback the operation.

  • Truncate table: The table content is deleted. You do not have the possibility to rollback the operation.

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.

Click Edit schema to make changes to the schema.
Information noteNote: If you make changes, the schema automatically becomes built-in.
  • 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.
