TxEventQ is a newer implementation that is optimized for much higher throughput and lower latency, and it provides transactional semantics (hence the name). There are clients in all common languages, and you can set up propagation between databases, even across long distances.
Şeklen şöyleIt has three main parts:1. The ability for Java applications written using the Kafka API for Java to use the Oracle Database as a Kafka broker,2. The ability for the Oracle Database to provide Kafka REST APIs, and3. Connectors that allow the propagation of events between Kafka and the Oracle Datbase, and vice versa.

OCI offers a fully managed NoSQL Cloud Database, a robust alternative to Amazon DynamoDB, and a comprehensive Change Data Capture tool known as OCI GoldenGate.
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 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.
Oracle’s GoldenGate seamlessly orchestrates data replication from source to sink through remote capture processes, known as Extract and Replicat. The Extract process captures the data and records it to trail files. These trail files are then leveraged to create a Replicat process, effectively applying the records to the sink.
