最后kafka连接器jdbc-sink语法错误

问题描述

我有一个关于这个拱门的 jdbc-sink 的问题.

i have an issue about jdbc-sink with this arch.

postgres1 ---> kafka ---> postgres2

生产者工作正常，但消费者有错误:

the producer working fine, but the consumer has an error :

connect_1 |org.apache.kafka.connect.errors.RetriableException:java.sql.SQLException: java.sql.BatchUpdateException: 批条目 0INSERT INTO "customers" ("id") VALUES (1) ON CONFLICT ("id") DO UPDATESET 已中止:错误:输入 connect_1 末尾出现语法错误 |
位置:77 调用 getNextException 查看批处理中的其他错误.

Kafka 连接 JDBC 5.2.1

Kafka Connect JDBC 5.2.1

我尝试降级 jdbc 驱动程序和融合的 kafka 连接，但仍然出现相同的错误

i tried to downgrade jdbc driver and confluent kafka connect but still have the same error

推荐答案

解决了这个问题，因为我在 postgres1 中创建表时，我没有将 id 设置为 PK 值

solve, the problem coz while i create a table in postgres1, i did not set the id to a PK value
