>             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.
