Open Schema Task

An Open Schema task is used to open a Schema in a Session without loading the associated data from that Data Store. This can be used if you just need to perform Schema checks and want to avoid the unnecessary overhead of loading any data. It is commonly used for a Schema Transformation task's Target Data Store, as that only requires the Schema to be opened, not the data to be loaded.

For each Open Schema task, a Data Store must be defined.

By default, an Open Schema task accesses all classes included in the Read and Commit. To override this, un-check the All Classes checkbox within the Task, and select the required classes from the drop-down list that appears.

To use the Open schema task:

1. Navigate to the Sessions workspace.

2. From the Navigation Pane, select a Session to edit.

3. Add a new Open Schema Task, or select to edit an existing one.

4. If configuring a new task, select the Data Store to be used.

5. If you want all classes to be used, leave All Classes checked.

   If not, un-check the box and select from the list of classes that appears.

6. Click Save.
