Manage Snapshots

This function helps you manage the snapshots of the ETL definition. 

Let's create a few definition snapshots to start with. 

On the ETL Process Designer page, select the Actions - Snapshot Management menu option. 

The right side pane renders the snapshot management functions as below. Provide a snapshot name OR use the Generate button to create a unique name for you. Click the Create button to initiate. 

The snapshot is created, and a confirmation message is displayed in the top right-end corner. 

Now, you can make some changes to the definition, like removing an ETL process step. Select the process step and right-click to remove it on the designer canvas. 

The ETL process step is removed as below. Navigate to the snapshot management menu option. Provide a different snapshot name OR use the Generate button to create a unique name for you. Click the Create button to initiate. 

The second snapshot is created, and a confirmation message is displayed in the top right-end corner. 

On the ETL Definitions page, select the definition from the table and click on the Actions-Manage Snapshots menu option.  

The ETL Definition Snapshots are rendered on a new page. The table below lists the snapshots created by the user and the system. 

You can use the drop-down list to select the source and target snapshots and then click the Compare button when ready. 

The snapshots are compared, and the differences are listed in the table below. You may use the button to switch between Table View and Image View. 

The Image View renders the snapshot differences using color legends as below.
