Targets: Supported targets include Kafka, flat files, network streams using plain TCP/IP or ZeroMQ, and discard output for testing.github.com · 1 Oct 2026
Database impact: The project is designed for log-based replication from Oracle Database with minimal impact on the source database.bersler.com · 1 Oct 2026
Offline operation: It can operate from archived redo logs and can run in offline mode while the database is shut down.bersler.com · 1 Oct 2026
DDL replication: OpenLogReplicator supports tracking actual DDL commands.bersler.com · 1 Oct 2026
Debezium: OpenLogReplicator can be used with Debezium CDC as a replacement for the LogMiner reader; the repository lists version 1.3.0 as the minimum and 1.9.0 as the recommended version for Debezium 2.x and 3.x.github.com · 1 Oct 2026
