table added
                 Key: FLINK-35128
                 URL: https://issues.apache.org/jira/browse/FLINK-35128
             Project: Flink
          Issue Type: Improvement
          Components: Flink CDC
            Reporter: Hongshun Wang
             Fix For: 3.1.0


In mysql cdc, re-calculate the starting binlog offset after the new table added 
in MySqlBinlogSplit#appendFinishedSplitInfos, while there lack of same action 
in StreamSplit#appendFinishedSplitInfos. This will cause data loss if any newly 
added table snapshot split's highwatermark is smaller.
