Question

我目前正在对Debezium postgres连接器进行负载测试，以了解它是否可以支持Aurora Postgres中的大量更改日志（以十亿计）。当我将100万条记录插入postgres表时，Debezium Postgres连接器失败，并显示以下错误消息：

似乎连接器不再支持include-unchanged-toast。有解决此问题的解决方法吗？

Answer 1

您可以修复Debrezium，也可以使用the option was removed之前的旧版本的wal2json。

删除该选项之前wal2json的GIT快照为here。

不过，请注意，该选项已被删除for a good reason。

Debezium postgres错误：不建议使用参数“ include-unchanged-toast”
