Welcome to oracdc

oracdc is a set of open source software solutions for the Apache Kafka Connect ecosystem designed to transfer information about changes in Oracle databases (versions 9i through 26ai) for further processing. This processing typically involves reacting to changes in the source system using event-driven architecture principles or performing data integration and replication to heterogeneous systems.

We recommend RedoMiner for most deployments. It has minimal database impact and supports the widest range of features. See the Getting Started overview for a detailed comparison.
