Informatica Mapping Insert Update Delete

There are situations where you need to keep a source and target in sync. One method to do this is to truncate and reload. However this method is not that efficient for a table with millions of rows of data. You really only want to: insert rows from the source that don’t exist in the target update rows that have changed delete rows from the target that no longer exist in the source Can you do this efficiently in a single informatica mapping?...
