Configuring pushdown optimization

Configuring pushdown optimization

To optimize a mapping, add the mapping to a task, and then configure pushdown optimization in the
mapping
task.
  1. Create a
    mapping
    task.
  2. In the
    Pushdown Optimization
    section on the
    Schedule
    tab, set the pushdown optimization value to
    Full
    or
    To Source
    .
  3. If full pushdown optimization is not available, select how Data Integration handles pushdown optimization in the
    Pushdown Optimization Fallback Option
    menu:
    • Partial PDO. Default. Data Integration pushes as much transformation logic as possible to the source and target database. The task processes any transformation logic that it can't push to a database. You can use Partial PDO only when you read from and write to Databrick Delta.
    • Non PDO. The task runs without pushdown optimization.
    • Fail Task. Data Integration fails the task.
    The fallback options are not applicable to mappings in advanced mode.
When you run the mapping task, the transformation logic is pushed to the Databricks Delta database.
