Problem:
What triggers the OGG extraction process to obtain data from the database?
Answer:
Only a specific data type will result in obtaining data from the database:

UDT 100% of the time GoldenGate fetches data from the database.
LONG,
Long raw,
CLOB,
BLOB Only if the row is chained. Otherwise, the data is captured from the redo log.
