[jira] [Created] (FLINK-38235) Unable to reliably detect newly added tables with MySQL CDC

Max Feng created FLINK-38235:
--------------------------------

             Summary: Unable to reliably detect newly added tables with MySQL CDC
                 Key: FLINK-38235
                 URL: https://issues.apache.org/jira/browse/FLINK-38235
             Project: Flink
          Issue Type: Bug
          Components: Flink CDC
    Affects Versions: cdc-3.3.0
            Reporter: Max Feng


It appears to not be possible to configure the MySQL CDC 3.3.0 source such that newly added tables will be read regardless of their creation time. It appears that:

scan.newly-added-table.enabled=true -> doesn't capture new tables in binlog mode
scan.binlog.newly-added-table.enabled=true -> doesn't snapshot new tables
both true -> Exception in the source factory

Our goal is that:
* When resuming from state, newly added tables are snapshot
* When in binlog reading mode, newly added tables are captured

Is this a limitation, or is there a configuration that works?
