Description

对datax 的 ob读写组件做了测试 : oralce 至 ob oracle
1)同一个配置文件支持 单表的 读/写 操作;
2)同一个配置文件支持 多表的读操作, 不支持多表的写操作;
会报:java.lang.RuntimeException: writing to multi-tables is not supported

由于文档中提到 table支持多表配置,使用 oracle 的读写组件做了测试:oralce 至 oracle
1)同一个配置文件支持 单表的 读/写 操作;
2)同一个配置文件支持 多表的 读/写 操作;

请问一下各位大神,这个是预期行为 吗? 还是配置问题?

Research direction

Start by reproducing the reported multi-table write with the DataX OB reader/writer configuration described in the issue, then compare it with the Oracle reader/writer behavior. Inspect the OB writer's handling of the documented multi-table setting and the reported RuntimeException. Done means determining whether multi-table writes are supported, a configuration issue, or a product limitation, and updating the relevant behavior or documentation accordingly.
