hive同步到高斯数据库使用datax全量同步

数据量大约4000w，同步到高斯。双边表结构一致 ，hive全tring，高斯（类似pg）全varchar
目前问题，同步数据到49.45%之后，不再继续同步，也没有报错。将来源数据的4000w limit至 500w可以同步成功，但是经查询datax没有同步数据量限制。

望大神指点迷津，不胜感激
Let’s bless each other with happy futures

Use the reported DataX synchronization cases as reproduction inputs: compare the 500w run that succeeds with the 4000w run that stops at 49.45%, then inspect the job configuration and available logs. Done means identifying the cause of the silent stall and documenting or implementing a verified fix for the Hive-to-Gauss transfer.
