I've just started trying out Debezium with the Oracle LogMiner connector against an Oracle Peoplesoft database. A sample Peoplesoft DB contains 79,000 tables, which the connector was failing to handle until I accidentally stumbled across
DBZ-3325, which mentioned log.mining.strategy=online_catalog. This parameter does not appear in any of the documentation that I could find. I was curious if that's intentional, or if a change would be welcomed. From a quick source search, it looks like the default is redo_log_catalog or this alternative online_catalog, but if I've missed something, I'm definitely not qualified to author this change.
