Description

insert模式执行第二次就主键重复了

Contributor guide

No contributing guide indexed for this repository

Research direction

Start by reproducing the second execution of insert mode against MySQL and inspect how DataX handles insert operations. The change is complete when existing rows are skipped, missing rows are inserted, and rerunning the operation no longer fails on duplicate primary keys.
