研究方向
Examine the HoodieTestDataGenerator class in the Hudi source code to understand how updates are generated. Review the TimestampBasedKeyGen implementation to identify which columns should not be updated. Check the JIRA issue HUDI 3152 for additional context. After understanding the logic, propose changes to avoid modifying certain columns during update generation.
