What is the default behavior of TiCDC if I create a replication task without specifying the configuration file in `--config`?

If you use the cdc cli changefeed create command without specifying the -config parameter, TiCDC creates the replication task in the following default behaviors:

  • Replicates all tables except system tables
  • Enables the Old Value feature
  • Only replicates tables that contain valid indexes
