Component Simulation

Run an ETL project in simulation mode to monitor and validate the transformation process step by step.

Data flow is visible on any link and within any component included. In simulation mode, many transformation components allow you to step through the current set of data and immediately visualize the result of any applied transformation.

• Initializing Components
  An ETL project can only be simulated after all its components have been properly initialized.
• Stepping a Component Multiple Times
  You can step a component multiple times during a simulation, to preview the behavior of a component with different property settings. Repetitive stepping does not increase the number of records delivered to the downstream component.
• Previewing Transformation Results
  When working in simulation mode, you can divide the entire result set of the datasource (as defined by a query in the source or staging component) into data blocks, which contains a subset of records.
