Debezium: 0.10
Kafka: 2.3
Postgresql: 11.6 (docker: debezium/example-postgres:0.10)
Using a nodejs script to modify the pg database every 200 milliseconds.
Then, I updated "table.whitelist" by the REST API.
Then, I found that Kafka lost three pieces of data.
Attachment pg_loss.log is the full log : pg_loss.log
Follow is the Debezium-connect docker config:
connect1:
image: debezium/connect:0.10
ports:
- 8088:8083

Follow is the connector config:
{
"name": "test222_pg_inventory_1",
"config": {
"connector.class": "io.debezium.connector.postgresql.PostgresConnector",
"database.user": "postgres",
"database.dbname": "postgres",
"slot.name": "test222_pg_inventory_1",
"database.server.name": "test222_pg_inventory_1",
"database.port": "5432",
"plugin.name": "pgoutput",
"schema.whitelist": "inventory",

"decimal.handling.mode": "string",
"database.hostname": "192.168.4.21",
"database.password": "postgres",
"snapshot.mode": "never"
}
}
Follow are the key time nodes:
2019-12-06 07:11:53.197: start editor the database, every 200 milliseconds
2019-12-06 07:12:21,533: update connector config (update table.whitelist)
2019-12-06 15:13:05.263: stop change data
