> Support Oracle CDC streaming with the XStream adapter
> -----------------------------------------------------
>
> Key: FLINK-39843
> URL: https://issues.apache.org/jira/browse/FLINK-39843
> Project: Flink
> Issue Type: New Feature
> Components: Flink CDC
> Reporter: tianfy
> Priority: Major
> Labels: pull-request-available
>
> Oracle CDC should support Debezium's XStream adapter in addition to LogMiner
> for streaming changes.
> XStream is required in some Oracle deployments where LogMiner is unavailable
> or not preferred. The connector needs Oracle-specific integration for XStream
> streaming, including XStream dependencies, stream source execution, LCR
> handling, offset advancement, and processed low watermark commit behavior.
> Expected behavior:
> * support configuring the Oracle CDC source with the XStream adapter
> * read streaming changes from Oracle XStream
> * advance stream offsets even when no user-level event is emitted for
> captured tables
> * commit processed low watermark only when the stream split is safe to
> commit, especially when newly added table scanning can suspend and recreate
> the stream split
> * include unit coverage for XStream stream source behavior and processed
> offset commit timing
