Unlike Active Data Guard, GoldenGate captures primary database changes
by reading redo records from disk, transforming those records into a
platform independent trail file format, and transmitting the trail file
to the target database. GoldenGate maintains a logical replica by
converting the trail file into SQL and applying SQL to the target
database. The target database is open read-write while synchronization
occurs. While this provides substantial flexibility as a replication
solution when compared to Data Guard, care must be taken to insure that
the target database is not modified independent of the source, unless it
is explicitly desired to do so.

variety of different pictures as heatmaps. I used TorchVision with
ImageNet1K_V1 mode...
