Description
Use COMPRESSDELETES

, the default, sends all columns to the trail. By sending only the primary key, Oracle GoldenGate has all of the data required to delete the target record, while restricting the amount of data that must be processed. This creates a net performance gain.

can be used globally for all TABLE
statements in the parameter file, or they can be used as on-off switches for individual TABLE
statements.
