Hi guys. Encounter checkpoint with long start delay. Look for help to investigate and tune. Thanks. Here is a Flink application to capture MySQL CDC event and write to Iceberg table. The checkpoint start delay can be very high sometimes. The start delay occurs in the source subtask (CDC source). Wondering what might be the cause and whether it can be tuned. It is still in initial snapshot stage and only 1 large table is included. No backpressure issue is spotted
