最后kafka连接器jdbc-sink语法错误

Question

我有一个关于这个拱的jdbc-sink的问题。

postgres1 ---> kafka ---> postgres2

生产者工作正常，但消费者有错误：

connect_1 | org.apache.kafka.connect.errors.RetriableException：java.sql.SQLException：java.sql.BatchUpdateException：批处理项0 INSERT INTO“customers”（“id”）VALUES（1）ON CONFLICT（“id”）DO UPDATE SET已中止：ERROR：输入connect_1 |结束时的语法错误 位置：77调用getNextException以查看批处理中的其他错误。

这是我的source.json

{
"name": "src-table",
"config": {
    "connector.class": "io.debezium.connector.postgresql.PostgresConnector",
    "tasks.max": "1",
    "database.hostname": "postgres1_container",
    "database.port": "5432",
    "database.user": "postgres",
    "database.password": "postgres",
    "database.dbname": "postgres",
    "database.whitelist": "postgres",
    "database.server.name": "postgres1",
    "database.history.kafka.bootstrap.servers": "kafka:9092",
    "database.history.kafka.topic": "schema-changes.inventory",
    "transforms": "route",
    "transforms.route.type": "org.apache.kafka.connect.transforms.RegexRouter",
    "transforms.route.regex": "([^.]+)\\.([^.]+)\\.([^.]+)",
    "transforms.route.replacement": "$3"
}

这是我的jdbc-sink.json

{
    "name": "jdbc-sink",
    "config": {
        "connector.class": "io.confluent.connect.jdbc.JdbcSinkConnector",
        "tasks.max": "1",
        "topics": "customers",
        "connection.url": "jdbc:postgresql://postgres2_container:5432/postgres?user=postgres&password=postgres",
        "transforms": "unwrap",
        "transforms.unwrap.type": "io.debezium.transforms.UnwrapFromEnvelope",
        "auto.create": "true",
        "insert.mode": "upsert",
        "pk.fields": "id",
        "pk.mode": "record_value"
    }
}

debezium / zookeeper：0.9

debezium /卡夫卡：0.9

debezium / Postgres的：9.6

debezium /连接：0.9

PostgreSQL JDBC驱动程序42.2.5

Kafka Connect JDBC 5.2.1

我试图降级jdbc驱动程序和融合kafka连接，但仍然有相同的错误

Answer 1

解决，问题因为我在postgres1中创建一个表，我没有将id设置为PK值
