Active Transformation:- An active transformation can perform any of the following actions:
- Change the number of rows that pass through the transformation: For instance, the Filter transformation is active because it removes rows that do not meet the filter condition.
- Change the transaction boundary: For e.g., the Transaction Control transformation is active because it defines a commit or roll back transaction based on an expression evaluated for each row.
- Change the row type: For e.g., the Update Strategy transformation is active because it flags rows for insert, delete, update, or reject.
Passive Transformation: A passive transformation is one which will satisfy all these conditions:
- Does not change the number of rows that pass through the transformation
- Maintains the transaction boundary
- Maintains the row type
