The record

Purpose: OpenLogReplicator is an open-source Oracle database change data capture solution written in C++.
Data capture: It reads transactions directly from Oracle binary redo log files and streams changes in JSON or Protobuf format.
Targets: Supported targets include Kafka, flat files, network streams using plain TCP/IP or ZeroMQ, and discard output for testing.
Database impact: The project is designed for log-based replication from Oracle Database with minimal impact on the source database.
Offline operation: It can operate from archived redo logs and can run in offline mode while the database is shut down.
DDL replication: OpenLogReplicator supports tracking actual DDL commands.
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.
Prometheus: Version 1.5.0 added direct Prometheus metrics, including counters for DML operations that can be tagged with schema names.
Filtering: Users can define basic DML filtering rules, such as processing only INSERT operations for a specified table.
Oracle support: The project announcement states that Oracle 23c is supported and that Oracle 11.2 through 21c have experimental binary XMLType support.
Integrity handling: If an expected redo log record cannot be decoded, processing stops immediately by default; users can force invalid records to be skipped and continue.
Support: Production assistance and proof-of-concept help are available by contacting the author through the contact form.
Data handling: Support guidance asks users not to send redo logs containing actual customer or personal data because this could create GDPR or similar legal issues.
Deployment: The Docker quick-start tutorial documents running OpenLogReplicator on a Linux 64 machine.
