> Key: FLINK-39841
> URL: https://issues.apache.org/jira/browse/FLINK-39841
> Project: Flink
> Issue Type: Improvement
> Components: Flink CDC
> Reporter: tianfy
> Priority: Major
> Labels: pull-request-available
>
> Oracle CDC currently executes ANALYZE TABLE before querying
> ALL_TABLES.NUM_ROWS for approximate row count during incremental snapshot
> chunk planning.
> For large Oracle tables this can be expensive, require additional privileges,
> and delay job startup. Users should be able to opt out when stale approximate
> row counts are acceptable or when ANALYZE TABLE cannot be executed in the
> production environment.
> Expected behavior:
> * add an Oracle CDC table/source option to control whether ANALYZE TABLE is
> executed
> * keep the current behavior enabled by default
> * when disabled, skip ANALYZE TABLE and continue to use ALL_TABLES.NUM_ROWS
> for approximate row count
