             Summary: Read incremental data for existing tables
                 Key: FLINK-37726
                 URL: https://issues.apache.org/jira/browse/FLINK-37726
             Project: Flink
          Issue Type: Improvement
          Components: Flink CDC
    Affects Versions: cdc-3.4.0
            Reporter: Yanquan Lv


1. We have scan.newly-added-table.enabled option to allow reading historical 
and incremental data for newly discovered tables.
2. And we have scan.binlog.newly-added-table.enabled option to allow reading 
data for newly discovered tables which is created in binlog reading phase.

However, we don't allow reading incremental data for existing tables because we 
haven't saved their schema information.
