[V主宰]

2021-10-20 17:34:26,381 INFO MySQL|debezium.sync.sr_test_mysql_master_1_gz_cvte_cn_3306|streaming Requested 'INCREMENTAL' snapshot of data collections '[seewo_group_prepare.t_teacher_group_prepare]' [io.debezium.connector.mysql.signal.KafkaSignalThread]

After insertion, only one log message produced above. 

operation step: delete kafka table topic manually, and then insert a execute-snapshot signal. kafka message as follow:

{"data":{"data-collections":["seewo_group_prepare.t_teacher_group_prepare"],"type":"INCREMENTAL"},"id":"333f3fe0c04248a68cf4b4e486756d0e","type":"execute-snapshot"}

Hi, I think, it's related to the CJCommunicationsException that happens at the beginning of the snapshot

OK, can this be released in 1.7 as soon as possible? This has a great impact on the Ad-hoc read-only Incremental snapshot, resulting in the failure of signaling to execute successfully, see more : https://groups.google.com/g/debezium/c/MRI9-qol6oU

I found that when there some connector property changes of 'table.include.list' (need to update connector config), the executing can take effect. Is this a bug when I just delete a topic and resynchronize without changing table.include.list?
