How Informatica MDM Hub Handles Delta Detection

How Informatica MDM Hub Handles Delta Detection

If delta detection is enabled, then the Stage job compares the contents of the landing table—which is mapped to the selected staging table—against the data set processed in the previous run of the stage job.
This comparison is done to determine whether the data has changed since the previous run. Changed, new records, and rejected records will be put into the staging table. Duplicate records are ignored.
Reject records move from cleanse to load after the second stage run.
