> Key: FLINK-37713
> URL: https://issues.apache.org/jira/browse/FLINK-37713
> Project: Flink
> Issue Type: Bug
> Components: Flink CDC
> Affects Versions: cdc-3.4.0
> Reporter: Yanquan Lv
> Priority: Critical
>
> OperatorCoordinator#resetToCheckpoint() is called even before
> OperatorCoordinator#start(), so that SchemaManager was recreated in
> SchemaRegistry after job failover.
> This will result in the loss of previously maintained schema information
> after restarting the job, leading to abnormal schema inference.
