DISABLE_APPEND_HINT — Specifies that you do not want the import operation to use the APPEND hint while loading the data object. Disabling the APPEND hint can be useful if there is a small set of data objects to load that already exist in the database and some other application may be concurrently accessing one or more of the data objects.
