tSnowflakeConnection

Opens a connection to Snowflake that can then be reused by other Snowflake
components.

tSnowflakeConnection Standard properties

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

The Standard
tSnowflakeConnection component belongs to the
Cloud family.

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

Note: This component is a specific version of a dynamic database
connector. The properties related to database settings vary depending on your database
type selection. For more information about dynamic database connectors, see Dynamic database components.

Basic settings

Database

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.

    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.

Usage

Usage rule

This component is more commonly used with other Snowflake
components. It creates a Snowflake connection and works with other subJobs that
reuse this connection using a Trigger
link.
Tracing Snowflake JDBC logs If you wish to merge the Snowflake JDBC driver logs with the logs of the
current Job, add this JVM argument,
-Dnet.snowflake.jdbc.loggerImpl=net.snowflake.client.log.JDK14Logger,
in the Run > Advanced settings tab of the Job you are running.
