Hi, When I run a blocking snapshot with kafka signal, Debezium did not stop streaming, Incremental data was still collected, including snapshot tables and other tables, If data modification occurs at the same time, and the snapshot of the same data is later than the streaming, the final streaming data will be overwritten, as follows:

For bug reports, provide this information, please:

What Debezium connector do you use and what version?

2.4.0.Final

What is the connector configuration?

{
    "name": "mysql_cdc_test_10000000000003",
    "config":

{ "snapshot.locking.mode": "none", "connector.class": "io.debezium.connector.mysql.MySqlConnector", "tasks.max": "1", "database.history.kafka.topic": "mysql_cdc_test_100000000000002_history.dy_test",   "transforms": "Reroute",         "transforms.Reroute.topic.regex": "(.*)", "transforms.Reroute.topic.replacement": "mysql_cdc_test_100000000000002_all", "transforms.Reroute.type": "io.debezium.transforms.ByLogicalTableRouter",   "topic.prefix": "mysql_cdc_test_100000000000002", "decimal.handling.mode": "string", "schema.history.internal.kafka.topic": "mysql_cdc_test_100000000000002_history.dy_test",         "schema.history.internal.kafka.bootstrap.servers": "127.0.0.1:9092",   "database.user": "root", "database.server.id": "100000000000002", "database.history.kafka.bootstrap.servers": "127.0.0.1:9092", "database.server.name": "mysql_cdc_test_100000000000002", "database.port": "3306", "database.connectionTimeZone": "Asia/Shanghai", "database.hostname": "127.0.0.1", "database.password": "xxxxx",   "snapshot.mode": "initial",         "table.include.list":"dy_test.dy_test_80_test_init_data_1",           "signal.enabled.channels": "kafka",         "signal.kafka.bootstrap.servers": "127.0.0.1:9092" }

}

What is the captured database version and mode of depoyment?

5.7

What behaviour do you expect?

Stop streaming of snapshot table

What behaviour do you see?

If data modification occurs at the same time, and the snapshot of the same data is later than the streaming, the final streaming data will be overwritten

Do you see the same behaviour using the latest relesead Debezium version?

yes

Do you have the connector logs, ideally from start till finish?

(You might be asked later to provide DEBUG/TRACE level log)
