使用选定的列更改 table - debezium 抛出 ArrayIndexOutOfBoundsException

Question

CDC table 的列数少于来源 table。当 debezium 尝试在 Kafka 中创建事件时，失败并显示：

ArrayIndexOutOfBoundsException.

历史主题具有完整源 table 模式的快照。这是 debezium 的限制，即 CDC 模式不能与源模式不同吗？

捕获 table 必须捕获源 table 中定义的所有列。

有一个 WIP PR https://github.com/debezium/debezium/pull/748 消除了这个限制。
