Kafka Connect 

Kafka Connect için açıklaması şöyle

This connector uses the Oracle LogMiner interface to query online and archived redo log files. That’s an Oracle specific way to stream both the DML and DDL directly from the redo of the database. This is similar to how the Debezium project reads the Postgres write-ahead log or the MySQL binlog.

Debezium 

Debezium için açıklaması şöyle

Debezium ingests change events using Oracle’s native LogMiner database package. Oracle LogMiner is part of the Oracle Database utilities and provides a well-defined, easy-to-use, and comprehensive interface for querying online and archived redo log files.

The first time the Debezium Oracle connector starts, it performs an initial consistent snapshot of the database to see its entire history. You can change this behavior by setting the snapshot.mode. After the connector completes its initial snapshot, the Debezium connector continues streaming from the position it reads from the current system change number (SCN) position in the redo log. The initial snapshot ensures that the connector has a complete and consistent data set.

The Debezium connector for Oracle Databases supports the following database versions:
Oracle Database 12.2 EE
Oracle Database 19.3 EE
Oracle Database 21.3 EE

The Oracle connector used with Oracle Real Application Clusters (RAC) is in Technology Preview (TP) for this release.
